Ever since the inception of the PlayStation 3, Sony has been saying the new machine has a 10-year lifespan, and they continue to hold that claim, as evidenced by SCEA Jack Tretton's speech at E3. But according to Crytek CEO Cevat Yerli's keynote in Leipzig today, he believes we'll see the PS4 and Xbox 720 "in 2011 or 2012." As reported by GamesIndustry.biz, Yerli was speaking about "The Future of Gaming Graphics," where he outlined the team's plans to release a new version of its in-house engine by 2012. And despite the overblown technological predictions, he said the current industry maximum of 1920x1080 resolution and 60 frames per second will remain until that time. And when the console discussion came around, here's what Yerli had to say: "The PlayStation 4 and Xbox '720' will arrive in 2011 or 2012, we think. But this is just our estimate - we don't know, and even if Microsoft and Sony told us, I couldn't say because it would be under NDA. But we think in three to four years' time, although there are good reasons why it should be 2010 already...but we'll see."
