I agree that is currently unlikely but Six Flags has experienced so much change I wouldn’t rule anything out. 10 years ago the general consensus was no more big coasters. 20 years ago they were plopping down big coasters all over the place. 30 years ago they didn’t even have that many coasters and when they did start adding more, they would move them from park to park.
So who knows, in 5 years we could see anything really.
For the time being I would just anticipate medium sized coasters with short ride times, cloned models, or anything you’d call a big coaster on a budget.
I’d really love to see our park get a launched coaster though! Maxx Force is short but I feel like that’d be a great fit!
