MK: By taking Laugh Floor and Former Stitches Great Escape buildings, could a new experience be built using both former attraction spaces? I do like the idea of flipping Laugh Floor to Stitch, especially if HS is getting a new Monsters show in Monstopolis. With already so much happening at MK, it doesn't seem likely either of it gets touched for a while though.
HS: AC dropping early was interesting, maybe more information or a rehash of that. I'd like to see the Walt Animatronic somewhere in WDW, so some sort of little show at the studios whether One Man's Dream, or at that upcoming Animation Building seems probable.
EPCOT: Journey into Imagination doesn't seem like a "now" sort of announcement, but an entire overhaul of the ride plus a new 3D show would be really cool. Not expecting it... I think I'd settle for the SSE actual update and enhancement as a very low bar, but would love the Mary Poppins small attraction added in UK area of WS.
AK: So much already happening, tough to expect anything else "new" news wise at this time; but you'd have to think the Lion King Flume will be in the park within 7-8 years.
