I think it has to be related to Kennywood.
Here is the wording used on the initial facebook post announcing Project 412:
"Something big is coming to Kennywood in 2019!"
3, 14, 21, and 33 are all CoasterCons that Kennywood has hosted. Isn't it kind of odd that 44 is the next Con to have it's host park announced, and that it was delivered during CoasterCon?
My theory is that is that CoasterCon 44 will be hosted in part by Kennywood.
