Intriguing... other than TomorrowLand (which excepting Space Mountain and the newly refurbed Star Tours, let's face it, is a mess), I'd say FrontierLand is definitely in need of helpit's been a shadow of itself since 1980 or so (Big Thunder was the last update to the land back in 1979).
Hopefully it's not just a rumor, and that we'll hear more about it soon!
