I decided to hop on Photoshop with the photo @ski4ever5 provided to try and make a mockup of what a possible full circuit layout would look like using what we've already seen with construction. I made a key on the right to denote what the colors mean. There's a chance everything I've marked here could end up being inaccurate, so take everything with a grain of salt.
I find the construction in the parking lot interesting, and how we haven't seen anything happen in the Ka plot (where the orange is scribbled) yet. It's the main reason why I'm really starting to think that this is going to be a full circuit coaster, since they could use that area for a return track as I've marked in the image. Either that, or they're saving that area and the entire area where Rolling Thunder/Zumanjaro's queue used to be to add another big coaster in the future.
A big reason why alot of speculation for a coaster in Rolling Thunder's plot of land would get shot down was due to Zumi's queue taking up that area, but with that ride now gone, I wonder if the possibility of seeing something in that area is now back on the table.
