Don't expect a ton of walls... Yet. Much of the work that will be done should be on backstage areas and areas outside the park initially. Toy Story Land for example won't need immediate work on the consumer side for sometime. Star Wars Land shouldn't be ramping up its construction for a while, so that too shouldn't be factor.
What will be more interesting to see is
Disneyland, once everyone gets a look at the closed Frontierland section.
