"We're not making announcements at E3," Hirai told a roomful of reporters at the recent CES 2012 show.
The five-year-old PlayStation 3 will have a 10-year life cycle, Hirai said.
For Sony's next console, the company will not deploy a streaming delivery system like OnLive, or fully cut out disc retailers like Best Buy and GameStop, Hirai said. While Sony has increased the number of games and other media available for download or streaming through its networks, most people cannot be expected to frequently download several gigabytes worth of data, which can be a time-consuming process, he said.
Like Microsoft has done with the Xbox 360 through Kinect, Sony is trying to extend the life of the PlayStation 3 through new accessories, like the Move controller wand, and initiatives like 3-D games. There are dozens of 3-D games now available, Hirai noted.
"We are definitely, from a Sony perspective, very committed to 3-D," Hirai said. "It's going to take a little while."
Sony CEO Howard Stringer, who also attended the gathering on Tuesday, compared the uptake of 3-D gaming and video to that of color television.
"3-D is waiting to happen," he said. "It's an inevitability. So be patient."
