It still shocks me that some people actually think SSBB has a chance of beating GTAIV's sales.

SSBB is probably going to end up with SMG like sales.

 

GTA 4 will get the biggest attach ratio in the history of video games.

by life time

12M(X360)

8M(PS3)

so in other words, you're predicting maximum lifetime worldwide sales of 12 million for the PS3 and 18 million for the Xbox360 (based of Super Mario Bros attach rate)

Although I suppose you might have means "attach rate of an unbundled game" which would be 24 million for the PS3 and 36 million for the Xbox360 (Based off Halo 2).

You heard it here first folks! leo-j predicts Xbox360 to outsell PS3, 36 million to 24 million!
