This came out last week and I thought it was an interesting hint of what may become of OTA digital broadcasting. The only way a service like this will ever take off is if the FCC enforces digital must-carry on cable companies. The plan is for NBC affiliates to create a dedicated digital sub-channel just for weather. I think WRAL was the first to do this. It isn't in HDTV but it is pretty cool! 8)
With most people being served by their locals now on dish it might not be quite as big a deal, but I agree. Having local weather available is important and since Cable does it, DBS should find a way. I don't count the current weather on 9500 or 100 as a true weather station.
