Sorry, ladies. And gentlemen. While America's TV shows fall over themselves to broadcast in HD, you'll be waiting a long time to see a sharper, more realistic David Tennant on your screens if producer Russell T. Davies has anything to do with it. His reason for television ludditeness? A High Definition picture would show just how cheap the new Tardis actually is.
With Who spinoff Torchwood having made the jump to HD this year, Davies says that that unpleasant experience was enough to make him realize that Who should stay lo-fi as long as possible:
I had a terrible experience on Torchwood. There was a lack of training and there was no extra time or money... We'd have to stop and rebuild the tardis. The flaws would show and it would take a lot of money to fix it. So we won't move to HD while I'm there.
