When asked in an interview with Develop, Quantic Dream's David Cage argues that new platforms aren't really needed until another 5 years or so. He insists that the problem is not so much technical as it is with I-MA-GI-NA-TION as Spongebob would say:

Well, we invest a lot in technologies and tools. We’re a very tools-centric company, with about 40 engineers all working on technology right now.

But to be honest, I’m not that interested in technology or the next generation of consoles. If we could continue with PlayStation 3 for another five years it would be fine with me. I think the main challenges are on the creative side than on the technical side.

Are there technical things I can’t do on PS3? Honestly, no. The limitation is much more about the ideas we have. When you look at the past, you realised that the technology evolved must faster than the concepts we rely on.

As an industry we have pretty much have been building the same games for fifty years, despite the platforms changing."

Although I am curious at what the next generation of platforms may bring, I gotta agree with Cage on this. No matter how beautiful the graphics and many gory kills you make, a game can get a little redundant and boring. Maybe I say this because I'm not much of a first person shooter fanatic, but there's nothing wrong with wanting a good storyline, and having some variety in the missions the game has.

He also says in the interview that he will be developing more games similar to Heavy Rain, which is good because it looked so interesting and entertaining. It's gotten some pretty rave reviews too. Oh and here's a GAME PROFILE just I wanted to try it out for the first time.
