"I go to Tokyo quite a lot and no one has referred to it--I think they have their hands full at the moment," he told MCV. "We just launched the PSP-3000 so we are still focused on this generation of the platform."

Reeves added that software for the four-year-old portable has been its "weakness," though he vowed that "PSP games will come--they just take a while longer."

"That's because developers, when it comes to placing their bets, have to choose PS3 and 360, then Wii, then DS, maybe even PS2 before PSP," he explained." It's the same at our internal studios, where the focus has been on PS3. They've also focused a lot on PS2 as well because we have to get the SingStars out for that format."

Though it has not seen a flood of new releases, PSP hardware has been outselling both the PlayStation 2 and PlayStation 3 in the United States since August.
