What I would like to see is:
Set in 2380, the rebuilding after the war is still continuing, the Quadrant has become very different though, with improved relations with the Cardassians (who were in dire need of help following the war) and the Romulans (after the Shinzon incident). )
I don't know. That may be a little too deeply rooted in the old timeline and continuity.
Certainly, I can't imagine that any new show would want to pick up on the Shinzon thing. That's old news--from a movie that most people never saw and many Trekkies are inclined to forget. No way are they going to want to reference NEMESIS, especially years from now when they finally get around to doing a new series.
