I think they are just as, if not more scared, of empty resort rooms however I do think the FL renovation is Disney's response for now rather than MI.
If you combine the new Liberty Square, with the potential FL renovation/additions to what is happening in Tomorrowland, and I think it all adds up to something much bigger and what quite clearly seems to be a comprehensive plan for the 40th. Jungle Cruise is also rumored to be getting an extensive refurb after the SM/TTA refurbs.
Can't wait for D23 Expo.
