I'm looking at some of the English screenshots, and see the Pokemon names are no longer in Caps Lock. C'mon, that's what I loved about battles! It may sound weird, but "BULBASAUR used Leech Seed!" has a better charm than "Bulbasaur used Leech Seed!". Plus, since I nickname all my Pokemon in caps, they'll look weird in this new game.
I know it's really insignificant, but just something I've always been used to has been erased. The game'll still be awesome, Caps-Lock or not :)
