I think Delta Vega being in the Vulcan system is PLENTY enough to establish that this is a totally different universe.
Or some planet renaming took place.
And so wouldn't it have been renamed with a Vulcan name if it's in the Vulcan system? Clearly Abrams tossed in all sorts of trek derived references with little thought about any logical consistency. He just wanted a slam-bam action movie with some familiar names. Fair enough for a reboot, but that still doesn't make it consistent with what had already been established. And as a reboot why is it even necessary to try connecting to TOS? Because he wanted some connection of legitimacy. But he fucked it up.
That doesn't take anything away from those who enjoy the film, but it is in contradiction whatever he may or may not of "intended."
