It's really not hard to do a little research and add it all up.
Aggressive spending in the parks:
$450 million for new Fantasyland
$50 million for infrastructure related Fantasyland updates including FoF, Pooh queue, Pan queue, Tangled restrooms
$50 million for infrastructure relating to the hub expansion
$50 million for new Star Tours (split of $100 mill for the entire project- of which plenty went into royalties and had little to do with actual R&D/ride system costs)
$300+ million waiting to be green lit for Star Wars (which I'm sure will end up being $450 when all is said and done)
$100+ million already green lit for Pixar Place
$50 million for Harambe's expansions/Kilimanjaro's infrastructure upgrades
$400 million for avatar/rivers of light (I'm sure over-runs will push it closer to $500 million)
$50 million for the Soarin/TSMM expansions (which will have over-runs like Disney typically has and end up being closer to $80 million)
$80 million for the Frozen expansion at EPCOT ($80 spent and waiting for an additional $40 million in fall once over-runs hit them too)
While it may be wildly overpriced and taking forever, lots of these projects are necessary and visibly improve the parks without being considered new attractions (though there are plenty of those too). And while everyone is busy ****ing and moaning over WDW's "supposed" lack of investment, they've spent or will be spending over $1.5 billion in improvements this decade. Of course I left out the over $1 billion in park related spending for MM+, which brings the tally to over $2.5 billion. Those numbers don't account for Disney Springs or the $100 million that they've allocated to replace/refurbish the bus fleet over the next decade (though that's on shaky ground at the moment, likely to be canned). There's also the investments being made at resorts, and the huge sums of money they're dumping into road projects (hint: roads cost more than theme park rides).
Whether or not this is a wise use of that money is a totally different question. WDI and TDO operate like NASA, $50,000 hammers and all.
But the money is being allocated and spent despite the claims of lots uninformed keyboard jockeys- it's just not always visible or what the fans want.
It's all out there in plain sight. There projects don't just happen for free. They cost massive amounts of money and are pretty much all necessary and good for the resort. New rides are nice too of course.
