Re: No reason the current cast couldn't do a TV series.
Assuming this film is well-received, I am under the impression that the franchise would continue with Abrams at the helm. And I don't think a TV series is the direction he'd want to take. Making a Trek film every 2-3 years sounds much more reasonable for him, his fellow producers and writers, as well as the actors.
Having so much Trek constantly on television for nearly 20 years is partially to blame for running the franchise out of steam in the first place. Going back to TV now seems like a poor choice. Let new material trickle out slowly for a while... I think the results would be better.
