About the shiny ST vs the grittier BSG, you can see that the Pegasus was a lot cleaner, had a newer feel and looked more like one of the new cruisers, sort of like comparing the HMCS Vancouver to the Protecteur, different eras and just newer stuff. The other ships in the civvy fleet look very star trek. Never figured out why the Cylons don't take over the civvy ships' computers, a controled ship is still a weapon.
As for the show, I saw a teaser for the next episode, it has the 5 cylon models that no one has seen yet, their faces covered with cloaks. I am calling it now that one of the models is Dirk Benedict, the old Starbuck and Faceman from the A-team.
Personal prediction, heck, they will probably digitize Lorne Green in if they could, and he's been dead since the 80's
