According to co-scriptwriter Robert Orci (from a Trekweb.com article):
"Our version of Star Trek is not exactly a prequel." said Orci "It is in some ways and you will have to see it to label it exactly. Canon, that is a word that was invented for Star Trek, meaning, does it fall within the continuity of this forty-year puzzle. But it was amazing when we went back to look at Star Trek, no one had ever done the story about how the original crew came together."
Interesting use of words at the start, "our version." Plus, the word "canon" wasn't invented for Star Trek, though it and Star Wars are perhaps the most well known examples of usage. One thing which is already established fact in the Star Trek universe is the original crew we are familiar with didn't all end up as part of the Enterprise crew at the same time. Chronologically, Spock was part of the crew for upwards of ten years prior to Kirk's arrival.
However, concerning these particular scriptwriters also wrote the Bayformers movie, I'm not surprised that things don't really make much sense. Nonetheless, I'm still expecting a good experience with Star Trek.
