Screamscape was sent the email that Selim Bassoul the new CEO sent to the company (You can read that email at the link below). It seems like Six Flags will be restructuring the company and returning to a reporting structure where the park presidents report directly to the CEO, which I would assume means they will have a lot more say/power in how they get to run their park.
