Right. Hiren, Shinzon and Donatra all died (at least in part) due to their office. Maybe Kamemor retires at some point, after a particular nasty Typhon Pact struggle? Who knows. Three years are plenty of time to revolutionize the universe again. On a sidenote, I'd rather see Geordi's uniform and combadge from VOY "Timeless" as the next uniform design.
I just thought of something what if David Mack decides to do something major that might freak the fanbase out in a different way, like say something similar to the cliffhanger of Plagues of Night?
