Theres no way on earth the Wii will drop to third place, its just too popular with a new crowd of gamers who have no interest in ps3/xbox.
PS3 will never sell as well as the 360 or Wii, simply because its out of most peoples price range still, untill it drops to 250-300 its just not going to compete. Not to mention it has pretty much 1 or 2 decent games out at the moment tops :/
Why do you think they're only 1 or 2 decent games on the PS3? Or dont multi platform games count? I was talking about next year not this one, GT5 will shift loads of consoles (2nd biggest selling game franchise of last gen) MGS4 will sell loads of consoles , as will the FF13 series.
