Whether it's on film or TV there will be more Trek. It will be in the JJverse (no going back to prime continuity folks) and may well feature new ships, cast and crew.
And it won't jump forward to the 24th century - they won't reboot TNG.
I agree with half of that. I can't imagine that they'll ever go back to the earlier continuity, but I can see somebody rebooting TNG one of these days. TNG nostalgia is bound to kick in at some point, especially as the generation that grew up on that show ends up in charge . . . . .
