Despite recent rumors, Sony says it will not be revealing a PlayStation 4 at E3 2012. According to Kaz Hirai, the company has no plans to talk about the next generation of consoles at this point. At a round table with reporters at CES, Hirai reiterated Andrew House’s December comments that said there are no surprise announcements incoming.
It looks like Sony is committed to the ten year life-cycle thing despite growing concern that by then, PC’s and possible competitors will have flown by and widened the margin of visual fidelity and memory specifications. A ten year life cycle for the PS3 would put us with a PlayStation 4 sometime in 2016, but many analysts believe its a matter of which company jumps first. Whether it be Microsoft or Sony, an announcement by either will likely spur the other on to reveal as well.
