Some of the animations I've seen so far are mostly similar. The Pokemon themselves are still mostly static during battle, though they all have a special little animation when they enter the battle--Mukkuru flaps its wings, for example. I suppose the attacks will have a little more flair in them now with the improved hardware. The attacks I remember most from the last games are sort of the 'end game' techniques, which I haven't seen yet, so I can't quite accurately compare.
