Sony's John Koller has said there are no plans to follow in Nintendo's footsteps and release a 3D handheld.
"Our focus on 3D right now is on the console," he told IGN. "There's a tremendous amount of opportunity on PlayStation 3 with 3D. The amount of interest in 3D from the retail side and game publishers is off the charts. We know we have a hit with 3D on PS3 and we're going to concentrate our efforts there."
Koller, who is director of hardware and marketing at SCEA, went on to question whether Nintendo is on the right track.
"I think it remains to be seen where Nintendo goes with 3D on a portable," he said.
"Having been in the portable space for quite awhile, I think it's an interesting move but one I'd like to see where they go from a demographic standpoint. 8 and 9 year-olds playing 3D is a little bit of a stretch given where some of our research is right now."
