That's the latest rumor title going around for Indy 4, which replaces Indiana Jones and the City of Gods.
I have to say that the more I hear about this flick the more apperhensive I am about it. I've read some rumors (which I won't repeat due to their spoiler nature) about the plot and I have to say that it sounds pretty dumb. I'm really starting to wonder if Lucas is trying to do to Indy what he did to Retard Wars. Really when you turn down a script about the Spear of Destiny in favor of this, you have to wonder.
