There's a big expansion pad left over west of Toontown once Star Wars Land is done. It butts up against some unused land north of Storybook Land and west of the Fantasyland Theater. This is the rumored location for the Frozen expansion at Disneyland, and I'm sure an Arendelle village of shops/retail/entertainment fronts the big show building where the Frozen E Ticket would be. Labeled as the grey box "FUTURE EXPANSION" on the Miceage map from last year....
If the One Disney executive structure really has been disolved as Miceage says, then perhaps TDA is now free to partner with Tokyo Disneyland on building a new Frozen ride instead of waiting for WDW management to approve something.
