Warhawk and Haze are likely to be the only games I am going in for PS3 this year... I was excited for several more but there are just too many good games coming out this year for 360 and PS3.
I really think the only BIG system movers will be GTAIV and Halo 3 this year (as far as next gen, Wii is in a whole different category.) But all the good games in general should jump start hardware sales.
(edit: forgot to post on topic. :P 35 - 30 - 25.... then when Madden hits(boom) and with subsequent releases sales will build into the holidays.)
I would cite regulation, but I know you will simply ignore it.
