Someone on Facebook also pointed out that Cedar Point's rides are always trademarked under Cedar Point instead of Cedar Fair, so under that assumption I think we can safely say this isn't for CP. If it's at all worth noting, Six Flags St. Louis's River King Mine Train also operated under the name Rail Blazer when it had the standup trains. Worlds of Fun is roughly in the same region so I'm wondering if any sort of attraction/aversion to WoF would be worth considering when trying to assign a home to this Railblazer name.
Also, Railblazer doesn't really fit the "they're coming" teaser campaign CP has been launching. We all know Tony Clark is the biggest troll in the amusement industry so I'd take anything with a grain of salt but if they're going with a consistent teaser campaign, a ride that hints at a group of something coming in doesn't fit a name like Railblazer in my opinion.
