Meet the World closed on June 30th. Since I haven't read it on this board, here's the news. A replacement has not been announced.
Also, as you all probably already know, Visionarium is closing in September. Replacemen: Buzz Lightyear's Astro Blasters. How sad? Too bad they can't bring back Magic Carpet 'Round the World (Circle Vision). BTW, when did the Circle Vision close?

I remember that Meet the World was originally supposed to be put in EPCOT Center at the Japan showcase, but it was sent to TDL instead. I would have liked to have seen it.
