Indeed, they essentially spent the last decade doing nothing and what little was done tended to be either OK or outright crap. That being said, I hope what changes are made are actual improvements rather than change for the sake of change which I fear might happen to Epcot.
They need rides that get people into the front of the park. I think the countries are fine and if they add 1 or 2 more countries that's great but its not really needed . The major issue is there is nothing to do. You go in and go on soaring and maybe test track those are the two rides. Figment is horrible (and he is my fav and deserves better) nemo is okay . You can completely skip the other side of epcot with the exception of test track. The ellen ride has been out dated for two decades and why waste time on it when you can go on a better dino ride at AK . Then you have that mission to mars with horribly outdated graphics. They need to give that an over haul . I'd say go VR for that and get CIG to make the cut scenes from it using their game . I mean get them to use this engine , record a demo loop put it in VR and use the simulation hardware they already put you in. You get an amazing rehab on a ride that is lack luster. The problem is that ride is going to sit there for another decade.
For a lot of people you go to Hollywood studios in the morning , knock it all out and go to epcot by 2 pm and spend time in the countries.
