This isn't official or anything, just thought i would post it.
Although Disney has already registered the domains for NationalTreasure3DVD.com and NationalTreasure4DVD.com, director Jon Turteltaub said that the filmmaking team will take its time on another National Treasure sequel. Though the second film ended with the question about page 47 of the President's book of secrets, Turteltaub responded in a press interview that the idea was not set in stone as the basis for National Treasure 3.
