Update: Joss Whedon has stated it's not real.
Kevin Feige did state there was no Avengers 2 post-credit scene (there is a brief tag scene at the start of the closing credits) as well as no Spider-Man for Age of Ultron.
Then what the heck is the above?
A video from what looks to be a foreign movie theater has leaked online claiming it's the actual post-credit scene from Avengers 2 featuring Spider-Man.
One way we'll know if it's the real thing is if YouTube takes the video down.
Fun to watch at least.
