Yeah, they've enclosed the sides of the FOF outdoor queue area instead of it just being open, and are apparently increasing the amount of space that was formerly switchbacks for additional locker area, so there's less lanes outside the main building than before. Firehawk's old maze has been altered and connected in so any excess queue for FOF doesn't spill out and congest the midway, because while it is somewhat uncommon for FOF to need much outdoor queue space, Orion being right there will certainly increase the ridership since it'll be exiting right by the FOF entrance, and it'll probably need that excess queue capacity for a while at least on the busy days.
Regarding the state of the Vortex plot, this recent drone video shows the rather trampled-looking empty terrain being fenced in.
They seem to want to basically bury Vortex at this point because the only mention since closing day was the addition of Vortex as a Nanocoaster Classic, and a limited commemorative ornament during WinterFest that used the same logo from the station banners and the Final Crew badges. They had said they might sell parts, like how they did the SOB track plaques and bolts, but nothing seems to have come from that. Maybe they think it would detract from promoting Orion or something.
