According to the boss of Sony's Worldwide Studios, Shuhei Yoshida, porting PlayStation 3 games over to the NGP is "simple and quick" - something which backs up the claims of Hideo Kojima, the creator of Metal Gear Solid.
"We had to make the development environment for NGP as 'easy' as possible. Today, many teams are familiar with the PS3 and are used to including a variety of effects in their titles.
"The three demos you've seen - Lost Planet 2, Ryu Ga Gotoku [Yakuza] and MGS4 - they prove porting is simple and quick, but it doesn't mean that's all you can expect. My view of NGP isn't just as a platform for porting PS3 titles."
If what Kojima said is true, about cloud gaming between the PS3 and the NGP, it could create an immense concept.
