It was announced today that sum of all thrills and storm struck will close in September.I think maybe I missed some news or announcement when I was at WDW last week ... not following how this could lead to major upgrades at Epcot. (Please enlighten me.)
(Sum of All Thrills is the build your own coaster simulator in an Innoventions building, right? If so, I've never done it myself, but my 9 year old nephew and brother-in-law tried it and weren't all that impressed.)
Innoventions will basically be nothing but the few meet and greets it has.
Epcot needs major work and work is heavily rumored. These closures could/should lead to major changes within the next few years at Epcot.
