1st - An MS phone jockey is the last source I would call official. I think more often then not Ms Cleo has a better idea of MS's upcoming product line then phone support does. If anything the page setup on Lik-Sangs website is better proof, but still not worth anything.
2nd - the AVIP port on the 360 flat out does not have digital signals present, There are jumpers to change the ports output into various formats (component, composite, s-video, scart, vga, etc.) all the possible combinations of jumpers have been tried and the console in it's current state does not output a digital signal AT ALL. This means that there either needs to be A. a hardware update, meaning only new versions of the console will be able to output in HDMI or B. the HDMI output will come directly from the HD-DVD drive, meaning no HDMI without it. There is a remote possibility that they could update the software on the encoder chip (not much is known about the chip) to include Digital output. I find it unlikely because if the chip was actually capable of digital output I believe MS would have it capable out of the box but disabled (by jumper configuration) until the cable was released.
3rd - having the HDMI output come from the DVD drive DOES NOT mean it's a complete stand alone player, the drive reads the content on the disc then passes it off to the Xbox to process it and actually generate the image, which would then pass it back to the DVD drive to where it would convert the data into the HDMI format before outputting. I HIGHLY doubt you'll see the component cables go from the AVIP back into the HD-DVD drive, considering that would be an unsecured signal and even if it was a specialized cable there wouldn't be anything stopping you from hijacking that before the HDCP was added... I don't see it happening.
4th - I don't think you'll see this drive get used in PCs for a long long time (if ever). Official drivers will not be released because PCs currently don't offer HDCP protection. it's impossible with todays hardware AND software. Windows Vista will be the first and only OS to offer it, and even then you'll need an HDCP capable drive, video card and monitor to view these discs on a PC. By the time that stuff rolls out I'm sure they'll also have much cheaper HD-DVD drives purpose built for the PC. The only way you'd see the 360's drive on the PC is if someone wrote custom drivers for it. And we don't even have fully functional drivers for the last gen Xbox's DVD drive, By the time someone were to figure it out it'd be pretty useless as again the cheaper PC equivalents will probably already be available.
5th - I think Foe-Hammers price estimates are about correct, $200 - $250 (I would say possibly even $300) would seem to be the most appropriate price point for a drive like this. Considering the stand alone players will start at $500 the add-on drive + console would need to be competitive with that. Core+HD-DVD would place it at $200, they could easily excuse a higher price considering you get a whole console on top of that. Alternatively they could price match a 360+HD-DVD drive to the price of the PS3, which could put it anywhere depending on the PS3's price point. Based on the hardware involved I think the $200-$250 is the most plausible price point though.
6th -I think the HDMI cable will probably completely evaporate if HD-DVD follows Blu-Ray's lead and drops the HDCP requirement.
http://slashdot.org/...6/03/16/2047251I've been all for HD-DVD over Blu-Ray since I saw their initial specs, but since Blu-Ray has dropped the HDCP requirement they're getting my support, that is unless HD-DVD follows suit.
You can bet that MS wont bother increasing the cost of the HD-DVD drive, or spend the money rolling out an extra cable type to add digital support if they don't have to.
