Thanks to our friends at Latino-Review we know what the post credits scene will be in Iron Man 3. It's nothing too crazy, it's more humorous than anything, but if you don't want it to be spoiled for you then I wouldn't read ahead.

Here it is...
It starts with a close shot of Tony Stark on a couch talking about his various traumas, obviously he’s talking to someone, as if he was seeing a shrink, the tone of the scene is light and supposedly funny. Then we discover that the person he’s talking to is Bruce Banner/Mark Ruffalo, who fell asleep because of Tony’s boring story. Tony remarks that Banner has been sleeping during the most part of his story and yells at him, and Banner just mumbles and says “You know, I’m not that kind of doctor!” Then Tony recalls another memory and resumes his monologue, and then we see Banner starting to fall asleep again.
I'm extremely happy that we'll get to see Banner in the film even if it's just for this little scene. Now, in case you're wondering what's going on with the rumored Guardians of the Galaxy Gemini Mark 39 suit reveal, it could end up as the mid-credits sequence like the Thanos reveal at the end of The Avengers. It's also possible that it's not going to be in the film at all. I guess we'll just have to wait and see! Thankfully, we won't have to wait much longer!
