So this is a little late, but according to ICv2, there are two Easter Egg endings to the new Wolverine movie that appear after the credits. ICv2 further says that there will only be one ending per print, so if you want to see each ending, you have to go to two showings of the movie. Click here for the full details.
If this is true, I'm a bit irritated by the idea of having to pay two ticket prices to get the full experience of the movie...
