I do agree that is something that we need to see. Right now, it's all trickledown. It's great, I love it. Lorelei's return to Asgard at the end of that episode (hinting that Loki is the one bringing her there) was awesome. On the other hand, without it going both ways, it can come off as glorified fan fiction. Fun for us, but maybe the movies wouldn't care. They need to trickle up (or even simulated trickle up by having a movie character appear in the show before the movie airs, even if the movie scenes were filmed first).
The best chance is Age of Ultron. It's a Whedon production, it comes right at the end of the season, they've had a lot of time to plan things. After that, you can hope, but you never know.
