I'm beginning to think this is completely different Universe,even before the Narada showed up. There are too many inconsistencies in technology for this just to be a different branch of the timeline from when the Narada shows up.
If that were the case, it would make...
No sense whatsoever that Spock Prime would warn his younger self about Khan, because if the timelines were truly separate, then Khan may never have existed or could be as different from Khan Prime as Mirror Brunt was from his usual self.
Plus the entire in-story justification for finding the Botany Bay and thawing Khan earlier - unless it was a timeline spinning off from Narada's incursion in 2233, there would be no need nor such effort expended by the writers in explaining how and why it happened differently to "Space Seed".
Nor would there be models of the NX-01 Enterprise and NX-Alpha on Admiral Marcus' desk if the technology was truly any different.
But this can indeed be a completely different timeline than the one we knew before, even pre 2233.
As all time-travel episode deal with either pre-destination paradoxes or a "restoring" of the timeline, no major event is changed significantly. In-universe, what we see as the prime-timeline is the culmination of all those time-travel events.
In the new timeline all the major "historical" events also occurred, but without tampering from the TOS/TNG/DS9/VOY-time-travellers, resulting in the year 2233 when we first see the Kelvin; a timeline where technology advanced slightly different/faster and the people are slightly different but similar.
