Agreed. The timeline
may have been parallel to the Prime Universe, running more or less the same with some minor variations - up until Nero, that is - but the Abramsverse was, otherwise, a totally different universe from the one we knew from day one. Had Nero not intervened, we would have had a thirty-something Kirk take command of the Enterprise
in the late 2260's, yes - but it would have been a slightly-older Pine, Quinto and the new cast, with the new patterned uniforms, on a not-quite-as-advanced Enterprise
that (inside and out) would have looked like a cross between the Kelvin
and the TMP refit (and not much like the TOS version at all).
This is a total reboot. The producers didn't want to call it such because they were afraid of alienating/scaring off the long-time franchise fans, but that's what it is. It is to the Prime Universe what the Ultimate Marvel Comics are to the regular Marvel line.
