Another thing to note about Fallen Kingdom is that it comes out after most of the major movie releases that summer. Infinity War, Deadpool, Solo, Oceans 8, and Incredibles are all out before it. The only competition it has afterwards are Purge, Ant-Man, and Mission Impossible, none of which are exactly major blockbusters. In that respect, I think JW:FK has the potential to stay #1 for quiet a while.
