And it will be set either in the JJverse or a new universe entirely. The prime universe is done and will never be seen on the screen again.
What makes you say that? You're not the first person I've read make the claim that the "prime universe is done," but nobody ever seems to base it on anything.
I sure I am not alone in feeling that I would rather see a continuation of the first ~725 installments of Star Trek rather than a rehashing of the old in a "new universe." I love the characters from TOS, but I feel their stories have already been told. We don't need a retelling with new special effects. Ditto for TNG, DS9, VOY.
A new TV series need a fresh start, not a re-start.
