I may be coming into this a little late, but here's my two cents:
If TNG gets a reboot, I'd prefer it to be still within the JJverse. However as much as I'd like to see a tv show in order to have LOTS of it, I think films are the way to go. Simply because it can maintain the visual standard made by the first film.
Additionally, if we wait to do films, say... 10 years (with a TOS era film ever other year) who would we possibly have as cast...
I foresee one rather logical
casting choice of Tom Hardy as Picard. Technically
he's already played him once, we KNOW he can act, and around that time he's getting a little closer to the appropriate age of Picard.
