Sorry people, but I think this is a totally bogus rumor. I see this alleged message in a "Guide Book" as nothing more than a warning that WOL will be closed down soon for a bit of refurbishment, but nothing more than that. I don't see Disney Brass spending money to update this one yet, mainly because in EPCOT years, WOL is still pretty young. And on crowded days Body Wars can still draw a decent line. Problem is, EPCOT hasn't had big crowds in years.
The biggest factor in all this needless hand-wringing you're all doing is this: EPCOT will NOT be needing anything else to draw more people on the East Side of Futureworld. Once Mission: Space opens, it's going to be a completely mobbed area of the park. I think it's bad now with just TT and it's line.
Crowds are going to return to Epcot once Mission: Space opens if M:S lives up to it's prehype and billing. And since there will be two immensely popular attractions side-by-side, logic dictates that some guests will naturally flow into WOL. Hence, an update of Cranium Command and a few new interactive attractions in the Fitness Fairgrounds might be all the new stuff we get.
Everything I've read speculating on what's next for EPCOT points to Disney Brass wanting some other "draw" attraction at another part of the park, like FutureWorld West or anywhere in World Showcase. Whether it ends up being a total reworking of Living Seas or the rumored Weather Pavilion or a Soaring Over attraction in WS, I'd bet all of you big $$$ that very little other than a quick cosmetic makeover will happen to WOL.
