Given that every ST movie so far has been progressing the story (Even going back to the '80's was progression, as it started and ended in the TMP timeline, same for First Contact), and that it's all been just that, progress (The introduction of the Sovereign Class, for one) I think I'm correct in saying that they are canon (And alot would agree). 
I did personally enjoy Enterprise, though I'm still on the fence about it being canon (Not bashing it, just genuinely unsure what to call it). And according to TOS, wasn't Spock aboard the Enterprise or another ship during Kirks academy days? 
No, you're right, I'm looking forward to American Pie: The Original Original Series.
