I was not aware of that. I would have been more accurate to say "whomever is Disney CEO."
Now that you've got me looking into, it sounds like he's retiring in the summer of 2018, though he's already starting to backtrack
on the claim.
Even if he does step down when they say, Iger has already alluded to Indy's future, so it's obviously being discussed. It's not like Disney's waiting for Indy 5 to get released to start plotting the next stages. He's already
involved with future Indy films in that sense.
