Christian Allen, an ex-developer for Halo studio Bungie, remarks in an interview that Killzone 2 - the flagship shooter of the PlayStation 3 - could be developed for the Xbox 360. If the devs wanted to, that is:
Oh yeah, Killzone 2 could totally be done on 360 if Guerrilla wanted to. The tech is there, if the team and the publishers were motivated, they could do it, just like Halo could come to PS3 if MS didn t own it. It really comes down to console exclusivity. The tech differences between the PS3 and the 360 aren t all that much; it s really about the delivery of content.
I'm no dev so I wouldn't know to what extent an Xbox 360 port is possible. Still, it's hard to imagine that some things, like polygon count, won't be sacrificed in a port.
