Jack Tretton, SCEA President, has said that Sony would be distracted if news of a new console came out this year. Sony plans on only being publicly focussed on both the PlayStation 3 and newly released PlayStation Vita.
"Right now, we're focused on PlayStation 3, and I've got another platform (PlayStation Vita) to get out the door in seven days, so I don't want to be thinking about trying to launch new technology any time soon," he said. "I want to focus all our energy on our console business, which is really just hitting its stride, and Vita, which really deserves a dedicated push from us. I, quite frankly, would be very distracted if I had to be talking about next generation hardware this year.
Maybe Sony is taking its first shots at Microsoft--who is rumored to be announcing their new hardware at this year's E3 2012.
