First I'd just like to clarify this thread isn't about which is better Wii or PS3 (We already know the answer to that [jokes]). The question is if Wii is changing gaming.
Now although some of you stated that games like COD4, GTA4, MGS4 have had great success. Nintendo is somehow selling more, look at the sales of Wii Fit, Wii Sports, Mario Kart, let me see if I can get the facts off vgchartz
