My local NBC and Fox stations still don't broadcast in full HDTV. They're DTV, but just 480p. So, the Superbowl (on Fox) will be underwhelming.
Last year, the local CBS broadcast the Superbowl in HD, but in the 3rd quarter, it went off air. That was nice. I think it's a conspiracy with the local cable company to get people here to spring for digital cable.
I have DirecTV, but I'm not in a big enough market for them to offer the local stations on satelite. Usually the CBS and ABC stations will switch to full HDTV for the priometime shows, but the podunk NBC and Fox still don't.
