At this point, there's probably an agreement in place, that prevents Star Trek coming back to TV (Netflix, still the same thing, serialised drama in the home), until after JJ Abrams production company are done. Another 2 or 3 years at least? Once another film after Into Darkness has been completed. Like October 1986 when TNG was first announced, and Voyage Home was still weeks away but unlikely to be anything other than successful. Something like this would probably have to fall between the cracks, while Bad Robot were mulling over renewing a contract. :\
I wouldn't assume that. Nothing prevents new TV. Last I read talks of a new animated Star Trek webseries is proceeding. Bryan Fuller has spoken of wanting to do a Star Trek live-action series. I just think Paramount is being cautious and have come to realise just how close they came to killing the franchise.
