I don't know why for such a supposed Sony bot, you give the benefit of the doubt to the other team so often.
Personally, I think the market is just much, much different in the US than it is in Japan, and the average, casual US player is much, much different than the average hardcore gamer. What GAF has been praising so much lately, as you even say, of the DS lineup, I really don't think are the kinds of things that appeal to the average consumer in the US. Nintendogs I think will be successful, and some of the traditional properties will as always be successful, such as Mario Kart, Mario Bros, Animal Crossing, but by and large, I don't think the majority of the DS's library appeals to average Joe in the US. Stuff like Kirby, Yoshi, and Wario Ware sell modestly to Nintendo fans, but quirky games (or non-games) like Trauma Center, Polarium, Meteos, Feel the Magic, Pheonix Wright, Electroplankton, etc., that make up a majority of the DS's library, aren't the kinds of things the average consumer over here is interested in, imo, even to the point of being things they would distance themselves from. I think Need for Speed and EA's sports games, even if they are on the DS as well, appeal much more to this person, and are much more associated with the PlayStation brand, and the PSP is pretty clearly seen as a very cool device by most, which is what seems to be more important to the average Joe casual.
At least, that's how I hope it works, because I want the PSP to be a big success, and the DS makes me cry. :'(
