With the information that half the footers have been poured, and seeing where the asphalt is already cut from the overhead drone shots. I’m almost 100% certain it’s the spinning Mack tower coaster I made a mock up. I was also think it might be supergirl themed. With the success of Superman movie and the upcoming supergirl movie new cedar fair management might be excited to use these IPs and actually do it right. It would fit with its neighbor Superman. Make that area Superman themed and move the board walk to the lakefront area.!

There are almost certainly many more footers to come. The footers we have right now are almost certainly just through the end of the inverted-launched-stall-thing. There will likely be a notably longer pull-out than your drawing suggests, followed by another, right-side-up launch/breaking segment and then a huge, very elongated pull-up into the main tower.
