What if Abrams fools everyone (except me, ya see) by making the story all about how the aged Spock--played by Nimoy--manages to RECOVER his lost youth by discovering the ACTUAL FOUNTAIN OF YOUTH, which he drinks from and then comes out played by the new guy? Could be, in fact, that Spock is actually MUCH older than we ever knew and he is restored to his youth and THEN joins Star Fleet and meets Kirk! In fact, it could be revealed that Sarak as not his FATHER at all but rather, his son.
It would turn all of Star Trek on its head and be the LAST thing that anyone expected (except for me, ya see . . . Well, and now you too).
