Gamers forcing move to HDTV?

I think we've heard this before, but in case you missed it the first time around, word on the street is that high-def gaming will be the primary driver for HDTV growth. At this point there's so much unclear in the HD-DVD vs. Blu-Ray war, so high-def gaming has to have some impact. I'd add increased high-def programming options as a key driver and I'd even go out on a limb and add increased Windows Media Center PC sales to the list.

What are we missing? What other drivers are forcing the move to HDTV?
