Assuming we have the same writers I think the next movie will feature the opening act being the Enterprise exploring a strange new world and completing a mission, similar to the opening of STID.
After the opening act we will see some big Klingon shit going down against some key Federation target, a space station or fleet battle.
The Enterprise is then despatched to help because fortunately it was on its way back to the core of the Federation anyway for some repairs.
During the course of the movie we find Khan is assisting the Klingons after being broken out of his 'prison' at some point because the Klingons want his help to capture the Genesis device or something. The Klingon dude will be called Kruge or Chang. The Enterprise will be destroyed using its self destruct sequence at some point.
