Mass effect 2 or FFXIII who will win?

S.T.A.G.E. said:

Mass Effect 2 will sell well over 3.5 M on the 360 alone. PC doesn't matter, because people pirate the hell out of PC.

What?

Mass Effect 1 barely cracked 2 million, and you think the sequel will do 1.5 million more?

Please don't say the userbase is larger. Please...
