Would'a, could'a, should'a.
We can lament what could have been all day. My concern is the current spending. They've certainly spent a lot recently, and have many things in the hopper, which we hope will come to completion without interruption.
It now makes sense why just before the announcement of star wars land, why they really did some belt tightening.
Star wars land, toy story land, Pandora, coranado, Caribbean and Gondolas are things we can all acknowledge as having had money spent in a quantity towards making a reality. Of those, the gondolas don't have a confirmation, but we have permits at least to say money is being spent in preparation for some sort of mystery project. If they are spending the money to move the water table stuff, we know they are least serious about whatever that project entails.
That is a lot of money to be spent. If one thing is for certain at Disney, if they spend money, they are expecting to make some in return, and somewhat quickly.
I think any sort of epcot investment(aside form stuff directly related to gondolas), has to be at least some sort of phase 2, after they've got some return on the investment of the above items. They may just be Pandora coming online.
I think the success of Pandora(or lack of) will determine if things are green lit for Epcot.
I also think logistically, the timing of these major project must also be considered. Until Pandora is online, I don't think they want to disrupt much more in the parks. With Pandora online, you may very well see a guest surge, and realistically even with it online, they don't have a net gain of acreage.
Aside for Gondola related stuff at the IG, I don't think you see anything happen there until Pandora is online, and there is a certainty of toy storyland imminently ready. Basically no more than two lands out of commission during a summer season.
That being said, I think you can get a quick win, if either france or the UK gets some sort of an attraction upgrade, that doesn't impact their daily operation. The other rumors for epcot may also be able to be accomplished with minimal impact. I suspect that will be a player in how and when things happen at epcot...along with the money side.
