^^I'm firmly in the camp that thinks the 'true' history of Trek was ended after the events of ST: First Contact. The new movie reinforces this nicely actually.
The Ent-E's effect on history radically altered and increased the early development of warp travel, the result of which is Star Trek: Enterprise, which is not a part of TOS- TNG(tv)'s timeline.
This evolves into STXI, which canonized Enterprise within its own framework. The world is now familiar, but drastically different with giant ships that are much more advanced then they were originally.
This renders all of the post-STFC history meaningless. But really I'm okay with that.
I agree with this... and it's what sets everything right in my mind. I gotta think that Cochrane was a changed man after interacting with Picard and crew, a more focused and driven man, with a new goal towards a kick ass Starfleet. Not the meandering uncertain organization that it was in TOS. Which carries onward to Archer, heavily influenced by our man Cochrane, and does the same to make a new kick ass Federation... all the pieces finally fit, I LOVE IT !! And it set a different timeline in motion. Think about it: TNG therefore affected the timeline once (for the better), TOS's Spock influenced it again, so the major players in classic Trek had a hand in forging this new improved Trek, and therefore, not so meaningless in the big picture. It makes me feel all warm inside.
And yeah, I said new and improved, cuz it is, and it needed to be, and I ain't gonna apologize for it... look, I love TOS, but it just seems silly at times and out-of-date and often it's hard for me to wrangle my feelings about that, to watch it thru my modern futurist eyes. I know it was filmed in the sixties, I get it, but to truly fit into all of Trek it simply no longer holds up. I loved the actors, the characters, the ship, a lot of the show was great. But it no longer fits... until now. It was from another time, literally and figuratively, and all Trek after that followed that same line. TNG seems just as silly, not until the 3rd season did it find its way but was still so behind in tech and concept for a 24th century depiction.
Now we have a Trek for the ages, one that will endure, and with this notion of how things actually changed starting in FC, I can feel good allowing TOS and TNG to exist in context but not bog down what we now have.
Enterprise is the new 'Original Series' and Star Trek XI is the new 'Next Generation', and I like that... I like that a lot.
