The prequels, no matter how many there are should end with WNMHGB and be tied into that again. If they try to retell it after that they are making a big mistake and I'm not interested. Who would be? That would be invalidating TOS and obliterating canon.
there is absolutely no chance that this will tie into old TOS. it's a different universe. what we will have is TOS-era with a weakened Federation, a weakened Klingon Empire, a Romulan Empire in a much stronger position and scope for infinite new stories. which is fantastically exciting and offers up all sorts of possibilities, like bringing in characters who we know from 'our universe' but who like Kirk, could have had totally different lives thanks to Nero.
and none of that will invalidate any of the original stories whatsoever. tbqh, I can't see how any Trek fan
wouldn't be interested
