There's a reason for that: they're not going to happen. Ever. And it's annoying when people keep bringing them up and can't get it through their thick heads. Thankfully it doesn't happen very often anymore. I guess they finally got the message.
No, most of these have been in the long term plans for many decades. It's planned to happen. Maybe not now or under current management or financial conditions, but the people who first laid down the planning for the resort all wanted these things to happen eventually. The attacks on the other board could be frustration over the fact that current management has ignored and disregarded the original visions, and have misdirected that frustration; and have rationalized it with religious denial.
Just look at what EPCOT has become. That's what happens when the vision dissipates. Tell any of the Imagineers who worked on its original attractions back then circa 1980 that EPCOT will become a permanent home and gardening convention with shuttered pavilions, they would probably not believe you.
It's that same attitude that has stalled monorail expansion. It's that same attitude that has the current system in poor shape teetering on a future state of disrepair.
It's that same attitude that has brought the company to do the unthinkable - selling off pieces of WDW parcel property. The latest victim to be announced to be sold off is Flamingo Crossing. This joins Celebration, Golden Oak, Cross Roads, Little Lake Bryon, the Four Seasons, and other WDW real estate properties to get sold off.
Additionally, no new resort hotel rooms have been added since the All Star Animation resort. However, existing resorts have become targets for conversation into Vacation Club time share units.
The highly anticipated New Fantasyland added no new atttractions, after taking attractions away; and, offered no E tickets.
Meanwhile, DLR over in Anaheim has done the complete opposite, actually adding new stuff and improving the existing attractions at the same time. They are really improving their attractions and updating them - hatbox ghost and explosive new BTMRR ending are but two examples of many that have yet to make it here.
