Both NVIDIA's GeForce 8800, which will be released on November 8, and ATI's upcoming R600 will have native HDMI support.
Actually, maybe Nvidia has this on its I/O chip but the bottom line is that the G80-based Geforce 8800 GTX and GTS have native HDMI support.
It's buried in the chip, along with native HDCP support. The firms just need to pay half a cent to Intel for a key embedded in the card bios and you get yourself a HDMI/HDCP capable card.
Nvidia and ATI are paying a $10.000 annual membership fee and they are willing to pay four cents for the HDMI royalty as well.
