I would also submit that Vortex typically had the shortest wait of any coaster at KI, along with The Bat. Part of that is good capacity but part of it is that it was a pain in the neck to ride. Literally. Poor Arrow Dynamics. They are losing what representation that they had in parks across the US. Still a fair number of them out there but definitely losing visibility. Hopefully, they keep The Bat running for a while. It's only five or six years younger than Vortex but it is still a very fun ride, albeit short.
On the plus side, Orion's lift hill has the first section in place along with track through the station area. I don't see the large crane that will be needed to go higher but I would guess that they will move along to the final brake run next and continue through the segments that are reachable with the shorter cranes. Or they wait until the big boy shows up and then construct the highest hills first. I don't know their schedule per se.
