"If you're looking at high def gaming, that was 2006 for us," said SCEA boss Jack Tretton, who reckons Nintendo's Wii U unveiling revealed nothing that spurs Sony into thinking it needs to release a PlayStation 4.
Speaking with Forbes on new hardware, Tretton said, "I think there's ground to be carved out for everybody. But I didn't see anything about Nintendo's announcement that said 'Oh, we'd better get working on rolling out a new PlayStation here pretty soon.'"
He went on: "Our attitude is kind of 'welcome to the party.' If you're looking at being a multimedia entertainment device, if you're looking at high def gaming, that was 2006 for us."
Besides that, Tretton explains that the PS3 has just started and that an evolutionary jump would, at this moment, be of minimal benefit. "PlayStation 3 is really just hitting its stride. And technologically, I don't think it's possible to provide any advancement beyond what we have," he said.
"What we've seen from the competition is trying to add features that already exist in PlayStation 3. We invested heavily in that, we rolled a very heavy rock up a steep hill, through the launch period. But now I think that all pays off, and we've got a long run way behind it. So, I wouldn't look for any discussion of a next generation PlayStation for quite some time."
The Wii U is Nintendo's next console, headlining with HD 1080p visuals and a controller equipped with a touch screen. Although Sony has said that the Wii U controller screen concept could be replicated with the PS3 and PlayStation Vita (the next-gen PSP).
Crytek has this weekend denied a rumour claiming it had begun development on next-gen hardware, saying its focus remains on current tech.
