The first IGP chipset from NVIDIA will be the C60 and it will come in the fourth quarter of this year or later. It's the Intel version of NVIDIA's C51 IGP chipset for the AMD Athlon platform which will be released soon.
The C60 won't be there to hit the market and compete the others but will jump in very shortly, you can expect 6200 TC like graphic integrated core and there are strong indications that this chipset will be able to accelerate H.264.
