To make another list of what seems to be on the possible outcome of SNW at this state, and if I make mistakes; feel free to correct me.
- Super Nintendo World seems to be possibly opening by 2022, as per what @Disneyhead pointed out.
- KZ (Barney, Curious George, Woody Woodpecker, Fivel), the KZ Parade Building (Venue used for Halloween Horror Nights and other various events), and possibly including the MIB Expansion plot and the land inhabiting the Men in Black showbuilding, total acre size in a guess = 20.65
- May of been pushed to 2022 to allow SNW to open alongside it's 1.5 element of the MIB plot and MIB Expansion Plot.
- @GAcoaster pointed out that ET may be counting it's days once again..
It would be wise to take account that it isn't impossible to rule out that they may be able to relocate the MIB Sprung Tent (used for HoBH/Chance) and Sprung 1 and 2 to new locations within this, which could reduce the size of the expansion plot by possibly one to two acres, depending on what they do.
As for attractions, three seems to be the most talked about.
- Mario Kart - SNW's Mega E-Ticket, using highly advanced technology in the project itself that would be groundbreaking, was apart of original pitch.
- Donkey Kong - The most known of the project in a way, Boom Coaster, track very similar to the steeplechase track that is seen from S&S at IAAPA this year. Ride Car attached on the side, allowing the ride to replicate elements from the mine cart levels from the DK franchise. Was apart of the original pitch.
- Yoshi - Next Gen Omnimover, seems to be on a lower capacity but goes around the area of SNW, and I think @Joe may of mentioned something about the ride car being animatronic but I am not willing to say that with confidence. Not in the original pitch
Not to mention, from what it seems like; D23 has seemed to wake Universal up from it's slumber, including expanding the footprint of SNW in Orlando to be including Men in Black and the Expansion plot right next to it, as a response to Galaxy's Edge from WDI.
What seems to be a somewhat possibility for that added land possibly including Pokemon into the mix. Pokemon, had a previous role in the original pitch, along with Zelda and Kirby, but was in more of a smaller role, similar to Zelda and Kirby in a way. And from what it seems, Zelda may be getting saved for Gate III as a headliner.
As far as my mind can reach, that's what has been read here so-far in regards to Super Nintendo World in Orlando, which seems to be the biggest out of the three.
I am very sure that I got some things wrong, so if people tell me and show where, I will make sure to edit things out to make it more streamlined.
