While NVIDIA wasn't showing off anything impressive at the show, there was a lot of very good NVIDIA news that we kept running into at CES. At CES we saw a mobile GeForce 8600 and 8400, later on during the show we learned a bit more about these two GPUs.

NVIDIA has two G80 derivatives designed to target the more mainstream segments: G84 and G86. G84 will be the base of NVIDIA's GeForce 8600 while G86 will be used in what is currently known as the GeForce 8500. Detailed specifications aren't known other than the chips are supposed to be 80nm, but expected launch date is around April or May.
