Or if at all, we'll get to see Galactica, Caprica is what, 58 years (?) before BSG so will the end of Caprica be the begining of the war hence we wont actually see it (Seeing as according to the mini series of BSG the Galactica it was constructed "...over 50 years ago during the early days of the Cylon War"), or perhaps something like in one of the "new" Star Wars films where you see the blueprints for the Deathstar kinda thing..
I wonder how much the Greystone company would have in constructing or at least helping out with the construction of something like the planets Battlestar.
I also wonder if we'll see anything "pre" Battlestar, so far all we've really seen are hot air balloons, a few prop driven things and the jets that Zoe refered too as "Vipers"...
And, how old is Adama meant to be in BSG, we know he served in the "first" Cylon War so would expect him to be over or around 20 by that point, he's probably 15 or so at the minute so maybe 5 seasons of Caprica, start of war, end of Caprica, year or so build the original 12 Battlestars, +"over 50 years" = Adama not far off 70???
