...I think what a lot of you are forgetting is that this is the first (set of) game(s) we get with customization. Of course there aren't going to be a million choices for us to pick from; GF's testing the waters. I'm sure that in subsequent games we will get more.
The only thing that surprises me is that GF didn't go down the 'gimmick' route very much. In other words, there aren't clothes from characters in the anime (Ash's outfits, Misty's outfit) or more Pokemon-themed ones.
