Here's the scene I'd like to see:
For whatever reason, the crew plus Spock Prime need Kirk Prime, they travel to the future, say about 480?? or so. As a bridge is careening down the side of a precipice, a transporter beam snatches the person falling to his death on the torn piece of metal. When (cameo appearance by) Captain J. L. Picard gets to the mangled wreckage, expecting to find James Kirk's body clinging on to the last breathes of life, he finds NOTHING. Last shot is him just looking at the wreckage at where in GENERATIONS, Kirk lie dying. (afterwards, He makes a memorial and goes on his way).
Then the title "STAR TREK: whatever they're gonna call it" comes in.
Kurtzman & Orci can come up with the rest (and reason). They get paid to do that. I did my part.
