Cedar Fair has trademarked the names Orion and Polaris. Both fit perfectly within X-Base. Also, it appears that this coaster could go under/over the Beast and possibly the Racer, with clearing and markers in both areas (sorry, I don't have any photos, I've been getting this info off of Kings Island Central Forums).
Also, there was posters up in Flight of Fear during WinterFest teasing "2020" and 355".
If this isn't a giga I'd be dumbfounded.
