Normally games on different platforms don't compete for sales considering they aren't selling to the same userbase unless we count into fact people sharing the same console. This is probably a minority so whatever. Only way they can hurt sales of one another is if hype of one cancels out hype of another giving it the cold shoulder to the mainstream.
Thus more than likely this is really not a gamble considering both are 2 big games. If ya need proof of what I'm saying check out GTA IV and Mario Kart Wii week.
