I've not seen HDTV in action. I can't imagine it's going to be that much better than standard TV, but that's because I'm a stubborn fool who's still stuck in the 16-Bit era.

Right now, I'd say that HDTV gaming isn't all that important. People aren't really looking at HDTV features as a reason to buy new consoles. By the time the next generation of consoles come out, HDTV gaming may well be a huge factor.

It'll be interesting to see, no doubt.
