Well, I don't know. The actual Thor/Jane 'ship was barely explored; there was a lot of talking about it and doing stuff because of it, but how much actual character development did the two get as a couple? Near zip, considering the affair's been through three movies (okay, "mentioned only" in Avengers). Honestly, the Tony/Pepper relationship got a lot more development in half the screen time. There was some Thorane (Janor? both sound stupid, I mean Thor and Jane; maybe Fosthor? Thorster? :) ) development in Thor 2, which seemed to end on a positive note. I think there's three narrative directions they can go with it:

(i) they get together for keeps -- Either they actually get married, or it's just resolved in such a way that the story is closed with them together; this option necessitates addressing the longevity/powers/responsibilities & careers problem. But even if Jane can be granted Asgardian longevity (why not, they can make a rainbow bridge and magic flying hammers, giving a human a 5,000-year lifespan should not be such a big problem), one of them would still have to majorly modify their career plans: Jane would have to study up to do Asgardian science on Asgard, or Thor would have to definitively abdicate his right of succession to stay as the permanent resident protector of Earth. Of course, Jane could also get bitten by a radioactive Spider-Man and get superpowers of her own; that's the comic book solution to any and all problems, right? :)

(ii) they break up for good -- Well, there's a dozen ways to write this; breaking characters up is not particularly hard, as opposed to plausibly keeping them together (cf. real world). They could split on irreconcilable differences (got enough of those going on, fo'shizzle), or circumstances could come between them, or a lame contrived reason, you name it. In any case, any well-done version of this would include heartbreak for one or both.

(iii) defer to next movie -- Not deal with it in AoU, but in a later movie, probably Thor 3. While this is possible, it'd mark the second Avengers movie where the TJ relationship goes nowhere. Also, Thor 3 isn't due out for quite some time yet, constituting a rather long wait for the audience. Whenever they would deal with it, the options would then reduce to (i) and (ii).

Option (iv), the status quo of an on-again off-again relationship remains indefinitely, i.e. basically nothing gets developed further, is dramatically unsatisfying and would make the writers look lazy, IMO.
