New story, if any exist.
If I had to rehash a story or two though, I'd go with Vulcans trying to reforge links with their Romulan brethren, meanwhile Klingons and Star Fleet are involved in numerous battles/border skirmishes. Romulam subterfuge is discovered to be playing a part in the impending war, Kirk manages to bring the Klingons to the peace table and Spock (Prime) does the same with the Romulans. This leads not only to a peace summmit, at Khitomer of course, but a full union between the three powers. Spock (JJverse) is now an ambassador, Kirk gives his 2nd star speech and we pan around the bridge to see a Romulan, Klingon and Andorian on the bridge. Roll credits, after main cast credits we get an all too familiar flash, a familiar voice rings out, no visual, just off screen.
