NBC Nightly news to go HD in March

NBC may have gotten off to slow start in the world of HD, well not as slow as Fox, but they are certianly moving along now. At this point they have as many studio shows as anyone in HD and now it appears they are going to be the first with a nightly news broadcast in HD. We have been wondering when this was going to happen for some time and while we are expecting to see many SD clips as well as SD segments like we do on Good Morning America and Today, we are always happy when we get more HD. At the same time we are not sure what to expect in regards to quality between out of focus shots and Weather Plus sub-channels you never know what you're going to get with NBC.
