I agree, Aang is definitely the last Air Nomad but you have to wonder if there may be other ways for airbending to return to the world other than through Aang's descendants (or from learning from the original airbending source (i.e. the sky bisions)). Bending as far as I can tell from the show is NOT genetic (or at least not entirely genetic) and can actually be learned given the correct circumstances (as in the case of Oma and Shu). Theoretically then we can assume that any non-bender (that is a person who has no prior affiliation to a bending style) can learn a bending style given the appropriate circumstances.

This is obviously hard to swallow given that many powerful and enlightened people are not benders in the show (i.e. the Guru, master Piandao, etc.). Which is why there is still a partial genetic requirement.
