Nvidia has released a whitepaper for it's ULP GeForce GPU line, citing advanced features and outstanding performance.

There is no mention of Tegra 3 (AFAICT), but this should give some insight into their future direction as well as a high-level perspective of architecture design.

The Tegra 3 will be a force to be reckoned with. I fully expect NVidia to hold the lead as they are planning yearly releases!
