Why is there a problem with using a 'rival' companies products anyway? If I worked in a car company (say, Jaguar) then I'd still probably drive a Fiat Panda unless I was specifically given a company car. If I worked for Apple then I'd still have my same laptop which runs Windows Vista, and keep that particular O/S. Does it matter too much, as long as the end product is good quality anyway? And it's not as if Killzone and Gears are really rivals anyway, any more than Halo and Gears or Final Fantasy and Star Ocean are rival series. I play Gears, Halo, Lost Planet and god knows how many other FPS's, but I've always wanted to work for Bungie as a developer, so where's the problem there? Same goes for the guy in this story.
