New Xbox 360 Coming with HDMI port?

We received this image from a source who wishes to remain anonymous. An Xbox 360 motherboard with a HDMI-port, interesting ...

Our source has seen 3 of these motherboards already, so it looks like Microsoft might be working on a new Xbox 360 version with a HDMI-port. However it's totally unknown when/if it'll be released to the public and if this will be included with all packages or only on the Premium.

Or, who-knows, maybe it'll be for a 3rd package ... maybe even with an internal HD-DVD drive after all, to compete with the high-end PS3? (but that's pure speculation and MS PR recently denied working on an internal HD-DVD).

A digital output would certainly come as good news for those out there with new HDTV-sets and it could be pretty useful for the HD-DVD addon too, certainly if those movies will ever be HDCP-protected (Image Constraint Token flag). However people who already paid $400 for their 360 might feel less happy if Microsoft releases this soon.
