I don't see a problem with the trailers as far as the introduction of Aura goes. Weiss for example is a Dust-user, which doesn't really affect Aura (but kind of messes up Dust, I mean have you seen any Dust-users use anything close to what Weiss used in the trailer [besides ice]?).

Yang's weird fire thing on the other-hand was a completely unexplained power at the time, so the introduction of Aura actually helps explain it, or at least gives an excuse.
