PS3 zealots are only happy about this not being exclusive to the 360 anymore, not happy to be able to play the game. I was thinking this would do well as its a great game but the more I read from those types on this site I think the game won't sell well at all. A wasted effort released to an ungrateful fanbase.
For the record, as a 360 only owner I would STILL pay full price for MGS4 if it came over. And, from what I've heard, its surely no ME2.
