Looking at Gemini, I must confess I could totally see it being the next Cedar Point coaster to go. It has aged past forty, it is neither particularly tall nor fast for its park, its layout is approximately as cookie-cutter as layouts get, and it is clearly evident that coaster technology has progressed a lot since it was built. Plus, it does take up a lot of valuable land.
But on the other hand, it seems like it does its one job phenomenally well. It doesn't go upside down, isn't particularly forceful, isn't so big as to be intimidating, and its capacity must be completely insane with those 4 trains à 30 riders. It's close to being the ideal coaster for those who don't feel like going on the big ones, while also not being small enough to be "insulting" to those who have outgrown the kiddie rides. It's a stepping stone and a crowd eater, a non-thrill coaster in a park full of big thrills, a family coaster big enough to be outstanding in its category. Just as I ask myself "Why don't they tear this old ride down?" I find myself asking "What better thing could they possibly replace it with?". CP needs a stepping stone between the kiddie rides and the huge thrill rides, and Gemini fits the role perfectly. It's not a very fancy job, but it's a job it does well.
RMC-ing it would be a total waste, not only would it practically need a miracle to beat Steel Vengeance in that niche (in which unlikely case, Steel Vengeance would find itself outclassed), but it would also leave a hole in the lineup. I could sort-of see them renew the ride, though. New track, new trains, replacing all machinery, new sensors, that sort of thing. Improving comfort and reliability while keeping the essential ride intact. But I'm not sure if it needs it. So, to conclude this ramble, I think Gemini will be left as it is, to do its unglamourous but important job for many more years to come. I might actually rather want to see Magnum be replaced (it too is getting old, and as a thrill coaster its role would be easier to surpass with a new addition), or possibly Blue Streak (which seems like a lesser Gemini role-wise, and which I suspect has survived this long because nothing else could reasonably fit inside its footprint anyway).
