Is this is still being debated? Its a Reboot attached to the original continuity via a time travel plot device.
Whether its an alternate universe or whatever really doesn't matter, its just words to describe a narrative framework, it will never make sense because it can't, its not real. Theres the original series, and the reboot. The reboot is current, and where the new adventures are. The original is of the eighties, the nineties and the sixties. Modern Trek is made for a modern audience and this way is so much better than knowing that Kirk will die on that bridge helping picard, or that Scotty will crash into a dyson sphere.

Agreed. No matter how much they work it, write it, add to it outside of the movie it won't make a bit of difference. I doubt they're even going to bother with trying to include the established canon into these new movies. It really doesn't make a difference now. Head!Canon <3 I'll always interpret the events in the movie as Spock going back in time and erasing his own future and these new adventures are the result of his changed future. Parallel universes and all that other crap over complicate a pretty clear cut and simple story.
