NBC Nightly News on-line: HDTV next?

How timely is this since we were just discussing HDTV distribution over the Internet: NBC Nightly News is going with an Internet distribution on November 7. No, it's not in high-def, but that's not surprising as the program is not recorded in HDTV. It does open up the possibilities, however.

Every night at 10 p.m., the original content from the NBC Nightly News will be available. I'm guessing they've picked that time because by then, all time-zones on the U.S. mainland will have seen the program. It airs at 6:30 p.m. for me here in the Eastern Timezone, which begs the question: will they have an RSS feed so I can subscribe and have the shows delivered to me?

So what would happen if the Nightly News were filmed in high-definition? Sure it would likely be distributed via BitTorrent, but how about something more consumer-friendly or easier to use? What do you think: will we eventually see shows like this in WMV-HD or some other "mainstream" format? I'm putting "mainstream" in quotes for a reason; feel free to substitute DivX, MPEG-4 or what have you in lieu of WMV-HD.
