Ps3 will win. Sony consoles have always been this expensive and Nintendo consoles have always been that cheap. If Nintendo didn't win last time because of the cheap-ness, it also won't this time. 70% of the gamers love playstation and they will continue to do so. Ofcourse MS is supporting Nintendo, saying people should buy a Wii isntead of a Ps3. Sony is their biggest rival.
While I am a nintendo fanboy, my opinion is not biased. It's an educated geuss. I honestly think WII will win, or come in a close second. 360 will be last IMO.
This is it ^^ Xbox 360: Halo all the guys who love halo will buy it PS3: Socom ----> totally going to win Wii: Mario ^^Its fun but think its not going to help Nintendo
