Nintendo will have an advantage over 720/PS4!

If you want to really get technical there are at least 4 major vendors which would be capable of doing the graphics and which hold numerous substantial I.P. whilst also containing the development talent to produce something that complicated.

1. AMD first choice
2. nVidia
3. IMGtech (handheld, biggest handheld GPU maker), another option for a Wii replacement. They make the PowerVR series IIRC.
4. Intel

BTW I wouldn't be too hasty to write nVidia off with Sony. From what the rumours say, the PSP2 has a Tegra 2 chipset in it. Maybe Sony is pissed at how delayed it is or something, Charlie wrote an article on that.

 

I had considered Imagination Technlogies and Intel but I don't think their tech will be up to it within 3 years. Intel won't have discrete graphics until at least 2014 (Larrabee doesn't perform well enough outside HPC yet), and their integrated graphics and Larrabee both consume unreasonable amounts of power. Imagination's highest-end chipset performs worse than the Wii, which is itself five or six years behind PC cards.

Maybe Nintendo could use Imagination, but Sony and MS will want the most performance they can get.

Charlie says Sony did drop Nvidia from PSP2. Another reason why they'd be upset with Nvidia.
