Its possible it was a Mack Tower last November, and the outcry has been so bad they changed their plans. If they signed a deal for a Mack tower, since its a straight design, just about any other park could fit it. IMO my personal opinion is enthusiasts make up maybe 1% of the daily attendance at a park, so they don't really care what we think. At the same time trying to pass of a Mack Tower in place of KA was just a bad idea from the get-go, I don't think even the majority of the general attendance would be fooled.
But yet here they are digging footers. Which even if they decided for a different coaster type, they are starting with plenty of time for a 2026 debut.
I don't believe the reasons given for pushing back the ride given how much time is left. I am wondering with all the show cancellations across the chain, park closures ect, if they literally just can't afford the investment. As a small business owner I can tell you since around 2022 onwards business has been terrible, so it wouldn't shock me if Six Flags planned on 2026 and attendance has been so bad across the country they had to push it back to afford it. Or... they never intended for a 2026 opening, but why bother starting construction right now.
