Shatner appearance:
I also hope it's true and based on plot points that I've gleaned a cameo makes sense. Also, creating a debate over his participation (will he?, won't he?) would also make sense...
The following is speculation, but since some it it is based on spoiler info I'll hide it as a spoiler:
Spoiler:
We've heard that the plot involves Spock traveling back in time to the original series to try to fix the time-line. I'm assuming the the big baddie, Nero, has messed it up to destroy the Federation and Kirk. Obviously Spock will succeed in stopping him. Also it is obvious that his repaired time-line will be similar, but not necessarily identical to, the one we know from Next Gen, DS9, Voyager, etc. This will allow them to deviate from established continuity in future films. It also means that the surprise could be that Kirk is still alive after the events of Generations. I'm assuming that Spock returns to his own time at the end of the movie and is surprised to meet Kirk (who is supposed to be dead).

Spock, raising an eyebrow: "Aren't you supposed to be dead?"
Kirk: "Aren't you?"
Spock: "I seem to have failed in restoring the time-line. - Fascinating."
Kirk: "Spock, I'd say you did just fine. Shall we call this one close enough, or would you rather try it again until I'm dead?"
Spock, hiding a slight smile: "Your assessment is logical. As you put it, we will have to call this one "close enough"."
