I always prefer the "old" continuity, but unfortunately it isn't realistic.
I think it will be in the new JJ-Universe, produced by him and features the Original crew, but only after the three feature films are finished (and are in financial terms sucessful).
Better a JJ-Universe Series than no new Series.
No way would we ever get that cast on a regular series. But you are right, if they were to do a show, it's much more likely to be JJ-verse then Prime.
Probably a new ship, with maybe the occasional guest star. I nearly wrote a new crew on the Enterprise, but I think the execs would nix that on the hope of maybe getting another movie out of them. Or maybe JJ-TNG.
