I'll be honest, that interview looked like someone with absolutely zero access to, knowledge of, or influence over the sale deliberations trying to put on a strong face and project confidence to the local community.
IF she's correct and there's a bunch of competition, I think it likely spells doom for any hopes of an amusement or theme park on the site though. In my opinion, our only hopes were for there to be super muted interest and for a park operator to be the only one with a competitive bid (cornering Six Flags into not forbidding amusement development on the land) or for the county to refuse to consider any development on the site that isn't an amusement park use (which they've declined to do).
If Six Flags has their pick of competitive offers and a giant mixed use development (like National Harbor) is on the table as a possibility for the site, Six Flags is NEVER chosing to endanger their other properties in the region by opting to sell to a park operator.
