If you go to this page, you'll find a "View Clips" link that will show you
the promo for the DVD. I wonder if this means we'll see the commercial on TV?

I'd also like to point out that first day sales are important to the
companies which produce DVDs. If you're planning to buy the DVD, this means
that it
will count more in the eyes of the people who are controlling the eventual
release of Season 3 if you pre-order or go out and buy it on Tuesday.
