I would be very excited to see some of Fox's animated characters appear in the park. Anastasia, Fern Gully, Pagemaster, Ice Age, Rio, Epic, The Book of Life - these are all movies Disney will likely have the rights to, unless Blue Sky needs to be divested for monopoly reasons. I would be very excited to see them start popping up more than they currently do (which is pretty much just Netflix and Target), even if that is just some merchandise rather than getting the full Disney treatment Pixar characters have gotten.
With WDA and Pixar, Disney will likely sell off Blue Sky. Ice Age is their big draw but the box office for the last few sequels have been on the decline. Saw Ferdinand last night and thought it was very good but they are predicting the box office to fall short of projections. May be beat by Coco this weekend.
