Anything from CBS can be used (when agreed upon) anything from Paramount can not be used. So that means anything "Trek" after nemesis that has been filmed by Paramount and not CBS will not be in the game. IP and copyright issues as the two studios spit from one another...
(I think, its been a while since I had read up on the whole CBS/Paramount BS).
It's not a matter of CBS wanting to, even if they did. CBS controls the rights to things within the realm of TV, and Paramount things within the realm of films. Since the JJ stuff only exists in the films, CBS can't grant rights for it.
With all the threads floating around the forums complaining about Cruisers and DPS and beam weapons, I'd have thought a lot more people would be chomping at the bit to fly THIS ship, with DHCs and Rapid Fire and Scatter Volley melting faces left and right.
