Indiana Jones IV Titles

Although no official title has been declared, Lucasfilm has registered the following possible titles for the long-awaited Indy IV with the Motion Picture Association of America:
Indiana Jones and the City of Gods (rumors of this title have already circulated)
Indiana Jones and the Destroyer of Worlds
Indiana Jones and the Fourth Corner of the Earth
Indiana Jones and the Kingdom of the Crystal Skull
Indiana Jones and the Lost City of Gold
Indiana Jones and the Quest for the Covenant

Since all the major studios, their subsidiaries, and large indies register titles on the MPAA list as a measure of protection (those titles registered first get priority), odds are the eventual title may very well be one of these.
