I am with you on that, UnitedFederation. I hope that the fact J.J. was allways "more of a Star Wars kid" is an advantage for the new Trek movie when it comes to aliens. So far we spoted just one alien, am I right? On the photos showing the filming of the ceremony at Starfleet Academy there is a blue headed alien we never saw before. However, the overwhelming majority of Cadets is human.
In the end I guess the new movie will also show us a Starfleet consisting of humans for 90 percent. What we saw so far implies that.
