I also heard the ride was going to come back sometime in the future.
But I also heard from a CM at DL about 1-2 years ago that they were considering that to be the placement of the upcoming Incredibles ride. They were kinda in hiatus about the Incredibles ride. When we got out store newsletter about the ride, it said it was going to be in DCA. When we went in like 05 or 06, I asked 1 of the CM when they were going to start constuction for the Incredibles ride, she got out this little booklet that all sorts of information on it (I would love to get my hands on one of those!!), and said "September" of whatever year I asked her. Never happened. The following year is when I asked a CM in FL about the ride, and he told me it would go where PM used to be, but they were having a hard time becuse of the tracks, abd becuase the type of ride they wanted to make. I had originally heard it was supposed to be a bit more of a thrill ride kinda like Indiana Jones.
I personally am not a big fan of the Incredibles, but I do know they are making an Incredibles 2, Toy Story 3 (2010), and Cars 2 (2012, the year Carsland is supposed to open in DCA). We got his info in our store newletters as well, except about the Incredibles, a Pixar animator told us (we are the closest store to the Pixar studios!)
HTH!!
