Looking at previous patterns and decisions Tokyo DisneySea should get something new next. Perhaps the long rumoured Soarin attraction. But hoping for something more original not related to Pixar or Marvel.
Soarin has always been planned to go where the Roman ruins are in DisneySea to the right of the harbor. It's only a matter of time (and OLC are probably waiting for The Walt Disney Company to get off its butt and actually shoot the Soarin Over the World film).
Surely if Soarin was to be built behind the Roman Ruins it would require a brand new movie to reflect the surrounding theming. Perhaps Disney are waiting for OLC to make the first move. That way it can copy it over to the other two parks at the OLC's expense.
WDI drew plans up several years ago for Soarin, OLC just needs to pull the trigger.

We were sent over there with the message that only we would defend Disney quality.. We learnt quickly that the Japanese culture speaks to a level of quality that is hard to comprehend. They were all unbelievably skilled and willing to do the right thing.
