According to this article, if everything goes as planned, it should be completed by 2024 which imo is likely around the time we may see our Vortex replacement. If so, I think we'll see some nice economic boost to the general area over those next few years with the opening of this complex and a big new attraction at KI. Just my opinion and nothing is confirmed and I am still not sold on this actually happening knowing the history with developments similar to this. Honestly, I think if this falls through I think it would be cool if they could move this project to Kings Mills/Mason and have it near Kings Island and make it a "downtown Disney" like feel in the area. Just my opinion.
