Main problem: space opera costs $$$$, the audience is inherently limited. Hard to overcome that math. Also, CBS has no obvious reason to push for Star Trek
-Animated series on the Cartoon Network a la The Clone Wars
, which no doubt the new owners will move over to DisneyXD, so hey, Cartoon Network will need a replacement, right?
-Reduce the SFX related costs while somehow not losing the Trek-ness of it all. Would a Gary Seven series be appealing? How about a series set in the future that takes place only or mainly on a single alien world?
-The next movie is a huge success and someone, most likely Bob Orci, makes a concerted effort to leverage that success into a convincing pitch to CBS, which decides against all their ingrained corporate habits to take a risk for a change.
