RDM has maintained that destroying the pegasus will only happen if it serves a purpose, and not for shock value and he plans to keep Pegasus around for a long time.

Also, everyone that thinks Pegasus will be destroyed because of the original series should remember that Glen Larson had pitched Pegasus' return in the second season (infiltrated with humanoid cylons no less) and then, after the cancellation of 1980, proposed a new series based around Pegasus' escape and search for Galactica & Earth

So I think the Best will survive and what we saw in the prview was a freighter making a suicide run
