I'm also mildly concerned that the show will depict the Academy as a bit too small for budgetary purposes. We know there's plenty of NCO's on Starfleet vessels, but still, in most eras, one would expect there are thousands of ships in the fleet, which would mean hundreds of thousands of active-duty Starfleet officers at minimum (more likely multiple millions). Starfleet Academy should at the very least look like a large public university in terms of enrollment (say 50,000+ cadets), but I am guessing we'll see once again something suggesting only a few hundred cadets per class, despite how ridiculous that is.
