One of the last pillars of PS3 third party strength is showing signs of crumbling. While I once thought it highly unlikely that MGS4 would go to 360, a quote from Kojima studios during an interview at 1up makes a 360 port sound inevitable.
"Payton knows fans have legitimate concerns about Kojima Productions possibly compromising the game's ambition due to issues arising from concurrent Xbox 360 development -- divided resources, less disc space, etc. -- and he addressed those directly:
"I can tell you honestly at this point, we have not changed the game in any form with the idea of 'oh, we got to do this on 360.' Put aside whether or not we're developing for 360 or not, the game is built on the PS3 hardware, as you guys have known for the past two years or so."
In other words: if MGS4 comes to Xbox 360, it has not affected the game's development. This is the same game Hideo Kojima decided to produce from day one. Make sure to listen to the podcast for more from Payton and the 1UP boys about Snake, Xbox 360 vs. PS3 and more."
If MGS4 goes to 360, Sony will have no choice but to fall back to it's last line of defense, Fortress FF XIII. How long this once thought impregnable fort can hold is anyone's guess.
