Why do the cool colored PSPs only ever come out in japan. In the US they have like 3 colors, and you can only get the colors if you buy bundle packs for games you might not even like!!!!! In Japan they have pink blue red camo, and all these freakin colors, but here they have white and black! WHY IS THIS?

because sony is made in japan and its not woth the money if they make other colours in america if only a few people buy it. and oh yea more people in japan buy psps than in america
