Indiana Jones 5.. No Surprise!

In an interview with Fox News George Lucas let it be known that he was all set to do Indiana Jones 5 and not with Harrison Ford at the helm;

"I haven’t even told Steven or Harrison this," he said. "But I have an idea to make ShiaLeBeouf] the lead character next time and have Harrison [Ford] come back like Sean Connery did in the last movie. I can see it working out.

Its an interesting premise, but it does beg the question how many more Indiana Jones movies can we have before the novelty of 'a new indiana' wears off?
