24/7 HDNews
I think that many people should give HDNews a look if you haven't already. They have been on the air for 2 1/2 years (Voom and now Dish Network - Can you imagine the amount of HD footage they have in their library.). The MidEast Crisis coverage is strong, there is a lot more day-of HDvideo of national news events, and to supplement the lack of international HD footage, they seem to have come up with a unique way of presenting the world headlines using and SD/HD combination at the beginning of their show. They also are an actual news station, without the editorializing and skewing that the other networks exhibit.
Also, the amount of sports highlights that are shown rival anything on ESPNHD in my opinion.
To answer the question, when are the 24/7's going to go HD? Not for a long time...they may upgrade their field cameras and control rooms, but there are hundreds of affiliates out in the country and world that the 24/7 SD's rely on to get their footage from, and many of those smaller affiliates are not going HD in the news dept's any time soon.
That's my thought......
