So to sum up the information we have so far from this thread and others (with the sources)-
- "Major" Frontierland expansion close to being greenlit, though not yet (whylightbulb)
- Includes one "E ticket" (whylightbulb)
- The Riverboat probably won't be docked and should continue to be run (marni1971)
- Tom Sawyer's Island stays in some form, changes in size/shape/theme are unknown (marni1971)
- Country Bear Jamboree safe for now, seasonal overlays could possibly return (whylightbulb/marni1971)
- Separate budget from the main $3.5 billion shared between DHS, MK and EPCOT (marni1971)
- "Highly unlikely" to be the old Geyser Mountain concept (Lee)
- Will not include a raft ride (marni1971)
- Not Western River Expedition or a variant of it (whylightbulb)
- One area of "interest" is around Tom Sawyer's Island and Rivers of America (marni1971)
- Another area is west of Big Thunder and north of Splash Mountain, outside the train track (marni1971)
As for opinions, WDW1974 says he's unimpressed and disappointed by what he's managed to piece together, one assumes he knows something we don't at the moment. He didn't elaborate on what upset him about it however. Articos on the other hand said "you can be at least little excited", though that post was over a month ago and the project may have been altered and downgraded since then...
