A recent Passholder behind the scenes event confirmed that a new coaster will replace Viking River Splash, which has been closed since 2023(!), and a recent application was put in for its removal. https://www.facebook.com/permalink.php?story_fbid=pfbid02vYtw4A5HP6n5Bi5wNPT2776TsJx5SDUVr4kPWk2dmVT54ZXu46EjNwitqToXZdWWl&id=61567089908870 It's also said this will extend a nearby land, of which Ninjago would probably make the most sense (and it is a popular Lego IP). Legoland Japan are getting a Ninjago-themed Mack Spinner next year, so don't discount that as an option. Legolands California and Florida recent got indoor coasters from ART Engineering, space-themed, and I think the idea would be great for Windsor. The Chinese Legolands have been getting B&M Junior Inverts too, so a farfetched possibility. Could also be something completely different, especially given the challenging landscape of that area. Also worth noting that all areas will be refurbed in the next 5 years.
