The teaser is still live here.Assuming that was Galactica's hangar deck, redoing the set in CG gave them the opportunity to fix something that always bothered me a little, namely that it was so cozy. You could barely fit a Raptor into it, so where were those giant three-story shuttles supposed to park? Now it's about twice as wide and, as a bonus, the parking slots for the Vipers are multi-level and have neat little elevators built into them, which helps explain the mystery of how they were able to just push the ships from one flight pod to the other in the miniseries.
I knew the virtual sets would require a bit of stylization, and I feel like they've carried it off well. The fact is, this isn't James Cameron's Blood and Chrome, and they couldn't take ten years and eleventy billion dollars to make it look perfectly real.
The only production-design things I'm not quite sanguine about are the new-old Centurions (hopefully the old-old Centurions will appear along side them, since I really liked the multiple Cylon models in the Caprica finale), and the new-old Basestar (which looks suspiciously like someone took the top half of the Guardian Basestar from "Razor," duplicated and flipped it so it'd be symmetrical, then superimposed it over the TOS Basestar model).
