I’m sorry to say that will never happen! Just doesn’t make sense for Epcot to soar over California. My preference would be for them to do California full time at DCA and World full time at Epcot (actually I’d prefer if they did an updated version of World with less CGI and less distortion (if that’s even possible).
I actually want them to make Soarin’ Across America, but without the CGI. Then I would be fine. It is the CGI I hate. Also, show us something unique, not all the things everyone has seen 1000 times before. Most of California is unique. Most of World is not.
