"Steven and George and I are sort of agreed on a germ of an idea and we're seeing what comes of it. The process works like this: We come to some basic agreement and then George goes away for a long time and works on it. Then Steven and I get it in some form, some embryonic form. Then if we like it we start working with George on it and at some point down the line it's ready and we do it."

So even though they have the idea don't expect anything for quite a while.  Also Ford my want to reconsider calling ideas germs, just doesn't sound good.

The last installment in the franchise, Indiana Jones and and the Kingdom of the Crystal Skull, made almost $787 million dollars worldwide and introduced Shia Labeouf to the series as Indy's son Mutt.  I don't think I'm alone in saying that Crystal Skull was a horrible abortion of a movie.  So many parts had me cursing at the screen for disparaging the good name of Indiana Jones.  Also Harrison Ford is 67 now.  Sure he doesn't look it but he also doesn't look like he would be traversing the world fighting Russians and discovering aliens and whatever horrible idea they might make up next.  Also Shia LaBeouf infuriates me, so that certainly didn't help.  I hope this movie never gets to production and George Lucas gets stuck in a home for the criminally insane.  End rant.
