I think they're far enough away from the colonies now that any chance of finding another ship will truly be exceptional. Pegasus was explained because she was hunting the basestars hunting galactica. Spoilers and RDM have repeated said that future finds like Pegasus will not happen.

Personally, I'd like a one-off, non-arc episode about another group of survivors returning to the nuclear annihilated colonies and finding something galactica's SAR team may have left behind in case other survivors show up telling them that there are more human survivors.
