Makes sense as the last several GPU gens Nvidia made chips with very high power consumption which frankly just aren't suited for consoles.

AMD just has a better performance to consumption ratio these days.

It has been known for a long time that all three console makers will use AMD next gen.

Considerring how rumours are going round that the next gen of consoles are going to be "conservative", I wonder if Sony will look at using an APU to save both power and money.

Seems unlikely (especially for backwards compatability) but it's still a possibility if Sony want to cut costs.

That would be no PS3 B/C.
The only way that would be acceptable is PS4 is a HUGE leap from PS3.

Idk but I think the PS4 may have to have an Nvidia GPU to have BC.

I don't care one way or the other. Next gen is coming and im ready to blow my money as soon as they come out : )

I'm not sure that will be the case. I think all PS3 games are developed using API calls and no direct access to the GPU hardware so there shouldn't be an issue switching to AMD so long as the new card has a superset of the NVidia functionality.

i feel as if if sony are using Blu-ray again (god they better) then i want PS3 games to play on it.
if not i want an ultra slim PS3 in Blue.... in the UK so i won't mind having a pS3 and PS4 next to each other...I'm fussy and sony let us down

With consoles the engines are optimised using the GPU's coding, that is how they pump out more graphical "power" at the end of a console gen. Which is what bit the 360 in the but for BC this gen.

But it doesn't have to have a nVidia GPU to be BC, the chip was mainly Sony's design so an emulator could be made the problem comes in how much nVidia code is in the chip. And what games use it.

Of course it will use Blu-Ray. Most likely 100gig discs with a much faster BD-drive.
