Indy 4 gets a title?

Apparently Shia LaBeouf let slip at the VMA's that Indy 4 is called 'Indiana Jones and the Kingdom of the Crystal Skull'.

Hmmmmm.......

Could it be a Hoax along the lines of the Star Wars 'Blue Harvest' thing?

Or is it just the old 'anything would have sounded crap' syndrome. I'm sure 'The Empire Strikes Back' elicited a few groans when it was first announced.

Opinions?
