Bet they're going to have a serious fire sale on those things. My dealership isn't ordering any more because they've been given the official word that the Duramax is going to be available in the very early part of next year, if not sooner.
Also, from what I've heard, production of the current H1's have stopped so the line can be retooled for the Duramax H1.

If it's everything I think it will be I'll get a pewter wagon.
