It sounds like they've actually had a big plan in place to rejuvenate Epcot as a whole for the past fifteen years or so, but I think what happens is that they go ahead and enact some of the easier, cheap parts of the plan like shutter Innoventions West in preparation to overhaul or rebuild the building, and then of course the actual money to pull off the whole plan never shows up. Doesn't make it right, and it might be something of an oversimplification, but that's the sense I get.
