Remember when an analysts predicted that the release of Grand Theft Auto IV could derail the ticket sales of the Iron Man movie that releases this week? While the idea that big video game launches hindering movie releases is nothing new -- they said the same thing about Halo 3 -- we have one more prediction to make about the launch of Grand Theft Auto IV: it's going to put a serious damper on sales of the Iron Man video game. You see, they both come out this week. Sure, a game might steal money from a film, but a big game will definitely steal money from a smaller game. They will be competing for the same shelf space after all.
