Bringing back those features in B2W2 would've seemed too random honestly. It seems like something you'd do at the start of the games, not at the sequels, plus R/S remakes are hopefully coming up so they're probably saving them for the remakes.
Nevertheless, I like who posted about the sprites. I'd love to have seen new animations for all the Unova mons :3
If anything I think B2/W2 had too many features and tried to outdo B/W too much and kind of failed at that, but that's irrelevant, really. ;(
