Nah...the movie takes place over a couple of decades, from the time he's born, up to the time he becomes Captain. At least, that's what I've read about it. If it turns out to be insta-Captain, I'm going to feel nauseated. Abrams said he's going by the Original Series and movies, and that's it. No other source, professional or fandom, would be considered part of his story. So, technically, it doesn't contradict anything (I don't believe).
Well, actually, according to the original series continuity (that is, actual episodes aired), Spock was originally on the Enterprise, under Pike, long before Kirk set foot on the ship (Kirk was stationed on a different ship). Furthermore, McCoy didn't get assigned to the ship until sometime after Kirk took over as Captain. On the original series there was a different doctor for the first few episodes.
Similarly, Chekov didn't join the crew until sometime in the middle of the "five year mission."
So, obviously, they're using a different continuity than the original series which, granted, was always loose to begin with.
