thats a bit naive, MS is doing this to increase the XO install base. the game will surely bomb compared to being a multiplatform. i just don't see this game selling well this way.
You seem to think you're disagreeing with me, but you're not. My point was that Microsoft wouldn't throw money at securing (what's likely to be proven timed) exclusivity for the game if it didn't think the measure would prove to be financially worthwhile -- this in itself isn't just limited to Microsoft's cut from sales as the platform holder, which is what you appear to think I'm alluding to.
