Indeed... who ff-ing cares...
It\'s not about the maximum power factor.
It\'s about development dedication and that being doable + profitable.
Hideo Kojima\'s team is only 1 single team.
They devoted lots of money,time and effort into specializing in Sony\'s hardware.
It took \'em a year, 2 years after MGS2 SOL on PS2 to do an Xbox port, which was pretty crappy.
So, there you see it ; it\'s on PS3 and not on Xbox360 becuz Kojima\'s team is only able to focus on PS3 hardware becuz of time and specialization. No doubt, that IF they had the time and money, they could also make the game work on Xbox360 & being profitable.
THAT\'s all there is to it, really.
