In Any Given Mid Or Post-Credits Scene

The Marvel Cinematic Universe is known for its mid and post-credits scenes, with some big reveals coming in them – such as Thor’s hammer Mjolnir, the Mad Titan Thanos and… Howard the Duck.
With that in mind, a mid or post-credits scene does seem like the ideal place to reveal the whereabouts of Hulk, after he jetted off to parts unknown in a Quinjet following the final battle in Avengers: Age of Ultron.
Given that mid and post-credits scenes can be totally unrelated to the movie they follow, such a scene could happen after any upcoming Marvel Cinematic Universe offering – Captain America: Civil War, Doctor Strange, Thor: Ragnarok or even the new Spider-Man movie, for example.
