Great post. It should also be noted that with twice as many theme parks, you'd expect WDW to have roughly twice as many things on the list. The parks of WDW really lack when "attraction density" is examined, especially the often mentioned DAK and DHS.
Exactly, if our future looked a bit more like...
2012: Fantasyland Expansion (MK), Test Track 2.0 (E)
2013: Princess Meet and Greet (MK), Start of DHS Makeover/Monsters Inc. Door Coaster (DHS), Festival of the Lion King Relocation (DAK)
2014: Seven Dwarfs Mine Train (MK), Rhine River Cruse (E)
2015: Beauty & The Beast Show Replacement (DHS), North America/New Camp Minnie-Mickey (DAK)
2016: Tomorrowland Refurbishment Started/Stitch's Great Escape Replacement (MK), Imagination 4.0 (E)
2017: Little Mermaid Show Replacement (DHS), Mysterious Island (DAK)
2018: Monsters Inc. Laugh Floor Replacement (MK), New Japan Attraction (one of Bullet Train Simulator/Mt Fuji/etc.)
2019: Radiator Springs Racers (DHS), South America (DAK)
2020: Tomorrowland Speedway Updated/Tomorrowland Refurbishment Complete (MK), Universe of Energy Update (E)
2021: Star Wars Attraction (DHS), Australasia (DAK)
2022: New Major Tomorrowland/Adventureland/Frontierland Attraction (MK - would open late 2021 for the 50th Anniversary), New World Showcase Pavilion/Wonders of Life Redo (E - for the 40th Anniversary)
...then we would be a lot happier - we wouldn't be ecstatic (for example, MK probably needs a major attraction before 2022, and a Tomorrowland update should not take 4-5 years, and the parks need "more" attractions, not just "attractions being replaced").
But what have I really listed here?
8 new attractions (and not all major - probably 3xE, 2xD, 2xC), 4 replacement rides, 4 replacement shows, 2 meet and great areas, 3 new animal areas 1 pavilion and 1 new theatre over 4 parks, and 10 years - it doesn't seem like that would be asking
too much...
