I'm actually in DC. The way I understand it is that the analog broadcast and the digital broadcasts will be different. NBC via analog OTA or cable will be completely different coverage then the digital channel. Some affiliates may multi cast using sub channels and broadcast both via the digital channel. My local NBC station doesn't run sub channels, which has me concerned because I don't know if NBC has issued some sort of memo or policy letter forcing the affiliates to broadcast only the HD show on the digital channel. It shouldn't be a 24 hour delay either. The delay will most likely only be the time difference based on geography so that the majority of the broadcast will be in prime time. I've seen two commercials on TV so far talking about the HD coverage, it should be impressive. Although, we should probably be prepared for the worst...that way we won't be disappointed.
