Sony put a huge cost into the PS3, but everything the PS3 is now scales very well. The CPU scales well, add more SPUs and PPEs and you have a beast of a processor for far less cost than what the original chip cost to manufacture. Ram is ram it's always scalable. Blu ray is also scalable, I remember when bluray first came out they had a 37 layer disc in the labs, so even a tripple or quad layer disc will be more than enough for next gen for space. GPUs are always changing because of the PC space, they don't have to R & D much on that end. Everything in the PS3 you can just add more for a smaller cost than what it was to R & D the PS3 and it will be a beast of a machine. I don't see the PS3 costing more than 400 dollars at launch and I don't see it costing much more than that to manufacture. Plus Sony has been slowly building all these tools, slowly utilizing the CPU and GPU once they better automate code being spread over the CPU's cores its going to be amazing. The only thing that'll really screw them over is if they change CPU architecture, it'll completely waste all the R & D they've been doing on the PS3.
