Moves being animated to look like real world fights wouldn't happen. It would look too violent, parents would complain, and possibly affect gamefreak's reputation negatively. Or something like that.
It would be cool, but you have to remember that kids play pokemon, and parents would freak out over it.
The OP meant outside of battle , he even said that in his post...
So like when you use Fly with Charizard, you see Charizard coming out of the pokeball instead of the standard birdlike creature.
I think it is a nice idea, but won't happen. It will be too much data to put into the game.
