Old Spock spent a good deal of his life after ST:VI working on Vulcan/Romulan relationships dreaming of one day having the two different being re-united. While it's quite probable that Spock wouldn't have lived long enough to see such a dream come true the way things played out for him were tragic: the planet of Romulus was destroyed, even after Spock promising to help; there goes all hope for reunification.That's bad enough, but then Nero blamed Spock for not being able to save the Romulans and goes and destroys planet Vulcan in the past with Spock along for the ride.
Spock witnesses the destruction of both of the planets he was trying to re-unite.
There are some Vulcans still alive, sure -- but if a reunification were to take place now it wouldn't be a reunion so much as it would be one planet taking in a tiny percentage of another culture. Spock's a pretty collected guy so he might be able to be 'pleased' with that result but I'm certain it's nowhere near the scope of his initial dream. Considering all of the things Old Spock has gone and done since the Star Trek series started I think it's a pretty sad end for Old Spock. I suppose they could do something with Old Spock in the next movie, but as it stands, it's a sad end for him.
