She did appear in the latest episode, but i think they turned her even more into a "Find Waldo" character.
Well...apparently nobody reads the FiM wiki. She appeared in 19 episodes in s1. She appeared in 20 different episodes in season 2, and about twenty different times in episode 22 alone. She's only been in 3 episodes in s3. The behind shot in episode 2, in the crowd on the right in episode 3, and two derpy's appeared in the crowd simultaneously in episode 5. So yes, there has been a distinct lack of Derpy in s3. The reason is obviously because of the controversy over her speaking role in The Last Roundup, considering they altered that episode after the fact to change her voice, make her eyes less screwy and RBD no longer says her name.

But it certainly was no reason to remove her almost entirely from the show. :/
