Magnus: Robot Fighter and Ultron

I am hoping that the post-credits teaser scene after Guardians of the Galaxy will be some footage of Avengers: The Age of Ultron, just to give a tease of what that film will be like.  There is just so much that Joss Whedon is going to have to cram into the film, with all of the new characters and repercussions from the various solo movies. I know they are still filming and effects work probably hasn't even begun, but it would be nice to see something to whet our appetites for next summer.
