And don't forget the full ATX P5E-V HDMI. It's not available in the US, but it is pretty easy to get. Also, Asus has another G35 board that does not have HDMI. That makes four G35 boards.
I think sales of the P5E-VM HDMI have been pretty decent for Asus. If you go to Newegg, they list 321 Intel boards. If you click on Top Sellers, there are 30, and the P5E-VM HDMI is listed. If you sort by the number of reviews (which probably has some correspondence with total sales), the P5E-VM HDMI is listed as number 12.
At this point, I would wait for the 8200/8300. However, the P5E-VM HDMI was available in November, and 8 channel LPCM works very well, so people that bought one of these early will have been enjoying multi-channel HDMI audio for almost six months before the competition catches up. With 20/20 hindsight, perhaps a few more vendors would have built G35 boards.
