Last I heard, Cars Land is pretty much dead and it's between Monsteropolis and The Incredibles.
Monsters, Inc. is my lest favorite PIXAR film so I am hoping for The Incredibles.
If it is Incredibles or Monsteropolis, I would call the 2009 D23 from a WDW standpoint a complete screw up. Toy Story Land, Incredibles or, Monsteropolis could have been announced at the 2009 D23 instead New Fantasy Land.
The problem with New Fantasy Land is on multiple levels that included later on forcing Epcot to get Frozen. Frozen was made for Fantasy Land, not Epcot based on how Disney is presenting it in Norway. The 2009 version of New Fantasy Land announced turned into a mess that Staggs try to make it better by adding in the Mine Train and Storybook Circus Land. Pixie Hallow was a mistake to begin with and the Little Mermaid ride was a bust considering it being a 10 to 15 minutes the last time I was down at MK.
Fantasyland even wasn't the worst land at MK entering the 2009 D23. Tomorrowland wasn't exactly great at the time and still isn't. MK as a whole wasn't in bad shape compare to Epcot, DHS, AK without Avatar being announced yet at the time.
Star Tours: Adventure Continues announcement at 2009 D23 wasn't enough for DHS despite American Idol Experience.The Star Tours upgrade was great, but it was a band aid to a theme park that had a lot of issues at the time. American Idol Experience not meeting Disney's expectations didn't help matters.
The fact Disney is looking at doing 4 phases at DHS now, shows how screwed up the DHS was in 2009. By now, Disney could have done 2 of the 4 Phases done already based on the ips already were in theaters way before the 2009 D23. MK's only problem entering 2009 D23 was capacity, but DHS, AK and Epcot had bigger issues at the time.
