You just reminded me of something, I read an article in the paper saying that the Wii helps people too lose weght, I am being serious. Some lost about 2 stone for playing on his Wii for one month - about 90 minuted a day.
Anyway OGTAM most of the things in the article doesn't actually say it is a direct bid from Sony, but if GTA was to become a PS3 exclusive it would kill the 360 badly, just like the PS2 on the X box. No biased involved I actually thought the X box had better graphis but didn't have the games to take it through.
