Harry Potter
Nintendo (Pokemon, Zelda, Mario)
Minions (not that I want them but the movies are huge)
But also if F&F which is a dying IP (each movies keeps making less plus they are going to end the series soon) then it could be any IP. If it's a great attraction you will get people into the land, Bourne Identity is not a huge IP but the show people only have good things to say, WW is packed is based on a movie no one cares about. Mummy gets lines and while I know people love Brendan now, the series is dead.
But point is Universal doesn't own Barbie and I doubt they are going to pay others to use IP's when they have unused ones and more Potter and Nintendo I think will still draw people
