Is it though? I'm not denying they'll eventually do something, but I can guarantee you it won't be everything we are hoping it will be or even 100% whatever they decide to officially announce and present in concept art. I've seen how this game works over many years.
Don't forget whatever they do, will likely take 3-5 years even when the shovel hits the ground, which they should have started years ago. There is going to be a few years of what I consider stagnation at the parks which isn't good timing in my opinion. They'll probably introduce some new things (shows, parades, etc.) to help, but as far as "new" expanding lands and attractions go... we're probably looking at around 2030.
Also don't forget a potential CEO change and other budget cuts along the way...which is why I'm in the I'll believe it when it is built and opens camp. Don't get me wrong, I'm hoping for lots of new and exciting things...it' desperately needed...but I'm not convinced they understand that like we do.
