Bat was closed in 1983, Vortex opened in 1987. YouTubers have pointed out that Cedar Fair has been on a schedule of 3 years for new coasters starting with Banshee so I think 2023. It sucks to see Vortex go but my guess is by "end of service life" they actually mean "arrow Dynamics no longer exists and parts are expensive and it's not worth the cost as it's not popular anymore.". I think they wanted to axe Firehawk and Vortex but Firehawks Land was more desirable for Orion so they axed it first and then waited till Orion was announced to soften the blow. Lol I'm not gonna lie I was on the verge of tears all last weekend over the news. It was my first big coaster, with The Beastie or whatever it's called now being the first!
