I'd like to see a complete Universe blu-ray boxset, with all of BSG (inc Razor and The Plan), Caprica, and Blood and Chrome. Oh and the Face of the Enemy webisodes!!
It looks like that one may never happen, due to contractual disputes. That's why it hasn't made it onto any DVD sets so far. Given that the show is over and done, it's possible no one's going to bother trying to sort it out, either.
