Are those readers comments though?
Nope... those were the author's comments. The author though is pretty much just a random fan of science fiction with the ability to post so it's all pretty much the same thing. The author of that particular piece has no more say in the direction the show takes than I do.
Indeed, I suspect that rather than Smallville coming into line with the comics, the comics will be coming into line with Smallville more and more in the future. With media tie-ins like Buffy season eight soundly beating out a lot of the older comics the trend at DC seems to be to adapt their continuities to the other media to try and get readers. Batman's backstory was retconned to match Batman Begins around the time of Infinite Crisis and Superman/Batman brought in the meteor shower/freaks and they tried to bring in Chloe (who likely WILL be worked into the comics in whatever capacity she ends up on Smallville once the series ends and they no longer have someone over their heads spiking the story).
It doesn't say who canceled it, but it does sound like the decision came down from on high. Of course that doesn't mean that Chloe is going to have a "big reveal" but I like the spec.
Big reveal in the sense I intended it in my post simply meant that her final fate on the show is one of the few mysteries left in the series... thus whatever her fate is will be a big reveal to the audience since we already know what happens with Clark and Lex and Lana. Despite what some might think, it doesn't
necessarily have anything to do with Chlois.
There were other remarks made by Dan Didio (head of DC comics) that made it clear he'd had his neck stepped on by someone higher up the food chain (which means AlMiles just because no one else at Time Warner would care). The fact that it was able to be spiked virtually at the deadline point (quarter to five on a Friday with a Monday deadline) and after the issue announcing Chloe's appearance in the next issue had already gone to press also shows just who really has the power in the DC Comics/Smallville relationship... and it's not DC Comics. At. All.
And Lois Lane as the stupidest reporter ever. Lois Lane was one of the few female heroes girls had, for generations. Shall we next find out she always did sleep with her boss to keep her job, because she never even finished college? Yeah, that's a way better role model for girls. Use your tits, not your brains, and you'll get farther.
I know what I said above, but, that said...
There IS a very simple solution to this and AM IS signed for 22 episodes while Ausiello just reconfirmed what Craig has said; that ED is only signed for her usual deal. He added that there may be a slight chance that they could possibly use her in perhaps (wow, the only time I ever use that manly conditional clauses is when I'm trying to softsell a NO) one or two more episodes, but that adding any more episodes to ED's schedule would be extremely "complicated."
Knowing what I know of television production and having been reading up on the methods of storytelling from the guy who taught AlMiles (and at least one of PS3... I don't have educational backgrounds on the other three) how to write stories (i.e. Robert McKee) I think that bit of casting news alone says a lot about where next season will be heading (for those who might say that McKee didn't actually influence them all that much, let me pre-empt you with a single word... Triangles. McKee pushed triangles in dramatic storytelling a LOT... he praises them for the degree of complexity they can add to an otherwise simple/boring story. He even describes a four person interaction scheme as a double triangle of interactions).
Going off the story presented on screen, I'd say it's very safe to say that the only thing Chloe was done with, was being under Lex Luthor (sorry Chlex fans) and if they're using even an ounce of their screenwriting education, her unjust ousting by Lex was just a season finale cliffhanger (that got dragged out by more episodes) that will be resolved next season. Again, this does not
necessarily mean Chlois. It just means that the spine of Chloe's story from the very beginning has revolved around her pursuit of journalism and you don't resolve that story, one way or the other, until the end of the story... which is still 22 episodes away.
The only way that Chloe being done with journalism works from a storytelling standpoint is if its a part of her finally realizing some subconscious desire that has also been present since the beginning of the story and is in conflict with her conscious desire. There hasn't been any such conflict for Chloe... the only real conflict in that area resolved way back in season four when she decides to keep Clark's secret and not use it for her own personal gain. Since then the only forces of antogonism in her story have been entirely external ones she's struggled against while her internal goals have remained fixed. Even Jimmy is presented more as an obstacle to her ambitions than as alternative. The fact that came with there still being 22 episodes to go pretty much dooms Chimmy as surely as we've known by the narrative that Clana is ultimately doomed. It simply runs against everything that's taught in screenwriting courses for her to just decide one day to give up on her life's dream and go make babies with Jimmy Olsen.
Nois, by contrast, has been consistently used as a bit player and you can see it in the amount of interaction she has with the protagonist. McKee describes it as a solar system. Clark, the main protagonist, is like a star, with his supporting characters orbiting him like planets and the bulk of his interactions are indeed with Lex, Lana, and Chloe throughout the season. Meanwhile the bit players are like moons that orbit various members of the supporting cast and when you look at screen interactions, Nois, like Jimmy, clearly orbits Chloe, with occassional bumps into Lex and Clark and Lana.
Bit players don't get major onscreen plot arcs and never get the happy ending over a supporting character. In order for drama to work only another supporting characters or the protagonist outdoes another supporting character. There's just no way, by the way she's been consistently written, that the writers intend for Nois to be anything other than a throwaway role in the larger drama of Chloe Sullivan (just as Chloe is part of the larger drama of Clark Kent).
So while my spec about things like Chloe getting back into journalism and Nois not being all that relevant to the story next year (like that's something wild, crazy, and new... she's never been relavent) IS indeed spec, it is spec that is based upon an understanding of what the series has presented, knowledge that in terms of building a story the amount of episodes you have to work with makes a huge difference (hard to build momentum when the character is absent every other episode), and some insight into the methods of screenwriting that the people involved in coming up with the story were taught.
To sum up my conclusions based on the above factors... Chloe will get back into journalism, Chimmy will end badly (he proposed too soon), and Nois will again be relegated to an irrelevant relationship for the bulk of her episodes before ending badly herself.
