Would be nice, but doubtful sony will let one of it's most anticipated releases go to the competition without a fight.
I mean really there were roughly 3 reasons to buy a ps3:
1: The Metal Gear Solid Franchise
2: The God of War Franchise
3: The Kingdom Hearts Franchise
Those are the top three reasons people give me when I ask them to justify the price tag of a ps3. No way would sony let one f it's best selling IP's go without a fight.
