Even the handheld is not on the market, but Shuhei Yoshida , president of Sony Computer Entertainment Worldwide Studios seems very much the PSP successor to be convinced of the future. He said in an interview with Eurogamer.net are some statements about the NGP

"There is no clear competitor in the area in which works the NGP. The handheld will be established as a special device that people are asking for. NGP cannot be placed against smartphones. You can't make phone calls on it and it's too big to fit into your pocket."

Some commentators have suggested it's set to go head-to-head with Nintendo's 3DS when it launches later this year, but Sony doesn't see it that way.

"Compared to 3DS, it was very interesting – when we were designing the NGP we had no idea what Nintendo was going to do," Yoshida revealed. Aside from the 3D stereoscopic display, they seem to be keeping the same theme that they had with the DS – it feels like an update of the DS to me. Lots of choices we made were so different from their choices. It's kind of hard to compare the two, aside from the fact that both of them are dedicated gaming platforms."

That was the Sony boss expected to personally not a big kudos to the competition, should have been clear. But Yoshida said Sony and Nintendo had a common enemy: the cheap mobile game.

"We struggle with the same problem that makes Nintendo difficulties. It is up to us to show as a game developer and publisher of the people that the games are worth the money, and not like the competition a few cents. You cannot release the same content that you put on the iPhone for a dollar on to NGP or some other consoles and expect people to pay 20 times that."
