From Wired:
** emphasis mine **
So I'm thinking, Nimoy's Spock has discovered Nero's plot to change the timeline, kill Kirk and/or destroy Vulcan. In the process the timeline that we know has been completely obliterated. No more TOS. Nimoy's Spock, trapped in the past, must now work to reconstruct the mess made by Nero the best way he can, perhaps changing the course of many lives along the way to have "most" of history fall back in line.
By the end of this movie, it seems, are we going to be left with a Star Trek universe more like the end of "Back to the Future"? The main parts are the same, but the details have been changed?
And now consider this: The only reason this new alternate timeline/universe exists is because the original had to exist in the first place (just like BttF). The original is not disavowed. It happened. It had to in order for Nero from the original universe to go back in time, destroy it, and for Nimoy's Spock from the original universe to create the new timeline.
In other words, it's all good. The old stuff all happened. And the new Trek will move forward unfettered.
And, while connected to Gene Roddenberry's creation, this film is deliberately and unquestionably built in its own universe, constructing its story on the idea that the original Star Trek time line has been destroyed and must be reconstructed as closely as possible.
