'I go first Indy'

Looks like Lucas, Spielberg, and Ford have finally agreed on a script for Indiana Jones 4.

I think they have been working on a script for this movie for the last ten years. At one point I think I remember reading that Indy would be looking for his long lost brother. Or is that a figment of my imagination?
It will be interesting to see which bad guys Geriatric Jones will be squaring off against. My guess would be the soviets, but maybe they will pick something out of left field again like that cult that worshipped Kali in the second movie.

btw - What is with all the 80's movies getting sequels recently? Rocky, Rambo, Die Hard, Indiana Jones...
