Considering the competition (reruns), I think so. CBS tends to have a good track record with it's summer shows.And then the real question is can a 13 episode series last a 40 week hiatus for viewers until next June?
Also, being only a 13-episode season helps alot, as being inside the dome means they don't need as much filler as with 22 weeks, and not much filler to be had inside a dome.
