This means that there is one question that remains unanswered. The pre-E3 press conference that was held by Sony had a large number of technology demos - what GPU was used to render those if RSX is still in development?

Burkett discussed how NVIDIA and Sony had used an upcoming product with many similar capabilities to the RSX to demonstrate the capabilities of the Playstation 3 GPU. The demos at the show were running on NVIDIA's upcoming high-end desktop part, and also SLI systems. It is unclear whether these were based on the new desktop part that we've referred to as G70 in the past, or whether they were GeForce 6800 Ultra SLI combinations.

Hmm... Interesting...
