MGS will give the PS3 a massive ww boost I think, possibly spurring sustained ww sales of 250-300k for over a month and a permanent boost of 10-15% ww.

a permanent 10-15% boost for a console that should sell 10+mil this year is 1-1.5mil/year

so over 9 years (10 year plan!), that's 9-13.5mil boost for a game that has never sold 6mil on a much larger userbase...besides the few million people who already own a ps3 that will buy mgs4....so u  think that mgs4 will sell 10-15mil lifetime??
