I don't know what to do about it. I want the DVD, but Universal has announced it for HD-DVD as well. Unfortunately, I'm a BluRay supporter, and Universal is still sticking to their HD-DVD-only stance. I'd be kind of pissed if I bought the DVD now and a BluRay release was available later this year. Same thing for Serenity.
Universal comprises the biggest bunch of home video retards ever gathered.
