PS4 and Xbox 720 due by 2012, says Crysis firm
Just our guess though, we don't know anything!
The president of game developer Crytek has predicted that the successors to the PlayStation 3 and Xbox 360 will appear within the next three to four years.
Cevat Yerli was hosting a talk titled "The Future of Gaming Graphics" at the ongoing GC Developer Conference in Leipzig, Germany, when he said that “the PlayStation 4 and Xbox '720' will arrive in 2011 or 2012”.
He stressed that the dates are “just our [Crytek’s] estimate” and claimed that neither Microsoft nor Sony have revealed any juicy next-generation console development timelines to him. But that's what his company is working to.
Yerli's forecast is reasonable. The PS2 launched in Japan in 2000, the PS3 in 2006. You'd expect the next console to debut five or six years beyond that.
Although news of a next-generation Xbox 360 is few and far between, talk of a PS4 isn’t new.
Sony Computer Entertainment Europe's VP of Technology, Paul Holman, confirmed way back in 2006 that a PS4 will be developed  by Sony. Whilst Ken 'Father of the PlayStation' Kutaragi has previously rumoured  that a PS4, 5 and 6 will be created. What, no PS7?
