AMD's next generation graphic chip will support DVI and Display port. This is what the creators of the hardware and display industry wants to push as the standard.
As HDMI is a dual link DVI interface with audio capability, it should not be hard to add HDMI over DVI support on the list of features, but the main connector should be the Display port.
VESA has been pushing its standards for years and it looks like this is unlikely to change in 2008 and for years to come. It looks like Nvidia’s high end cards will also go Display port, but it is too soon to tell.
