Cedar Fair is still operating their parks even though they're under SF ownership so it's pretty unlikely that it's an RMC conversion or RMC project in any capacity... even though this is exactly the move they need to do. Like you said, with the 2026 World Cup coming up, it's a huge opportunity to pull in crowds, plus, with the rumored Mattel park coming to KCK they're bound to lose a lot of attendance in the future. They really need a stand-out coaster to stay relevant and an RMC conversion is the cheapest and most logical option considering there isn't an ibox coaster anywhere in this region.
I think the most likely move here is a Gravity Group pre-cut retrack. CF has done this to 4 of their wooden coasters in the past few years with great results. It might seem weird considering GCI just refurbed the ride but that was obviously a massive failure as it still runs rough, has a ton of downtime and doesn't pull in any crowds.
I'm really rooting for some sort of radical re-imagining of the ride. WOF has 3 wooden coasters as of now and refurbishing Timber Wolf won't really move the needle. Just knowing Cedar Fair and how they treat WOF, I'm expecting to be let down.
