I also was going under the assumption of "in this generation for Sony" and included GT5 and FFXIII into my thoughts.
If FFXIII is out as it was not a worldwide release and GT5 doesn't count as your poll only means up until the time GOW3 comes out then I change my vote to yes, as I can see it beating UC2, but it has no hopes of toping MGS4.
Sony actually ADVERTISED MGS4, so far I have still seen nothing for GOW3, or Heavy Rain, or WKC... (Outside of internet ads. TV, Radio, Billboards, etc)
Seriously WTF? Does Sony have a marketing department?
Unicorns ARE real - They are just fat, grey and called Rhinos
