Well, not THAT many parents bought Xbox 360s last Christmas. I mean, there were only 400,000 at launch, and most of them ended up being bought by the people who camped out in front of the store, only a handful of which, I think, were parents. I mean, there are something like...45 million PS2s, 15-18 million Xboxes and about 8 million Game Cubes sold in America. Thus far, there've probably been like...2 million Xbox 360s sold. Tops. The majority of people are still in the current gen, and soon, there's gonna be a scramble to buy an Xbox 360, and/or a Wii, and/or a PS3.
Once again, it's gonna depend on who has the games, and how many units are available.
