Disney CEO Bob Iger:

“We have done two, and yes they were really fine movies. I know Jerry Bruckheimer who produced them has had conversations with our studio a number of times about it, and there have been some developments along the way, but as of right now we have not green-lit as we say, a National Treasure 3. But I do know there is time and some resources spent on development. That's all I can tell ya.”
