Bashiok answered a few questions about Direct X 10 today. First up, will D3 support it?
[BLUE=“http://www.battle.net/forums/thread.aspx?fn=d3-general&t=363781&tmp=1#post363781”]We haven’t announced any final support for DirectX versions/system requirements. I’ll say that right now we’re not using any DirectX10 features, but we potentially could.[/BLUE]
Follow up questions got increasingly technical. Don’t take any of this as set in stone until Blizzard makes a more official announcement, much closer to the release date.

As far as I know though multi-GPU support is purely (or almost purely) a function of the drivers to throw alternate frames to each card, and as such shouldn’t be dependent on the software(game) whatsoever.
...I could just be wrong about SLi/Crossfire support. It just logically doesn’t seem to me like the software can make the call on where the frames are sent to draw. Whether there’s a performance increase or not is another thing of course. I don’t know enough about it though, I should ask a programmer.
