It'd certainly boost sales, I don't think anyone can deny that, but to such a large extent? I don't really think so. GTA 4 was a great game, but it wasn't on the level of previous GTA's. If Rockstar deliver a superb new addition and it is exclusive, then yes, but if GTA 5 is similar to the level of 4, then probably not.
