Just watched The Last Roundup on Netflix instant. Seems they changed Derpy's voice there too. Kind of a bummer. Anyone know if there is anywhere to watch the episode with her original voice intact?
Your best bet is the "Friendship Express" DVD- when it came out a few months ago, it had the original version. And, even when Shout Factory had to issue replacements to correct an audio glitch on a separate episode, they left "The Last Roundup" as is. Having said that, there's always a possibility that it could be replaced with the bowdlerized version in a future batch of DVDs- so you may want to pick up a copy sooner rather than later.
