I think the new movie franchise is a good start; but truthfully? I think Trek's best bet is a new animated series - follow in Star Wars' steps (while still retaining Trek's dignity - it can be done! Cartoons aren't JUST for kids anymore, you know...), and get a new generation of fans onboard.
Let's see the toys, the publicity blitz etc etc.
I think a new animated show is far more probably than a live TV series at this point, and potentially a lot better for the franchise.
Something set in the 23rd century? Star Trek: Titan? Something else? Doesn't matter - just make it good!!
