Director Gavin Hood revealed at a screening of X-Men Origins:  Wolverine that the film will have two Easter egg endings, which will provide additional footage after the credits.  The endings will reveal important info about characters.

The two endings will appear on different prints of the film, so fans won’t be able to see both without seeing the movie twice. 

The film’s ending is not the same as the one that was on the work print leaked earlier this month (see “Over One Million Wolverine Downloads”).
