I think that, with Thor being more relevant to the Marvel Universe, the writers will defer and not bring in Asgard and the Norse Mythos. The closest they will get is the one line that David said a couple of seasons back (and that was really more an easter egg reference to his role in the first Thor movie than to actually bringing the Norse Mythos to Once.)
