Well CBS' new studio at Washington and Dearborn will be HD. I saw a camera crew filming CTA busses last fall and I was talking with the cameraman in between busses, and they were shooting on Sony XDCAM even then, so all their "archived" footage from the past 12 months should be archived in HD as well. When I passed the new studio near the end of June, the interior finally had some sets up that said CBS 2 Chicago on them, so it could go live in the next month or two, granted it passes their internal testing. As far as FOX, they got that new set several years ago which seems like it would lend itself to HD (all the LCDs and Plasmas they have) the question is simply when. Lastly, I know I watch either ABC or now even NBC simply cause they're in HD and why watch FOX or CBS when they're not.
