I have no idea if the above you tuber sources are accurate but what is mentioned certainly sounds plausible and has been the rumoured plans in other places.
The new rumoured rides would suit the park with two family thrill rides and a new kids track ride and retheme of the buffalo, the rumoured Viking Village theme I also like this theme for the park. As for the 2023 rumoured coaster would be interesting if they did go with a Gerstlauer family coaster like Firechaser express at Dollywood, with forwards, backwards and launch section. Again fitting the family thrill market, although they already have the Vekoma boomerang in the same area with the backwards section.
Its great to see the looping group investing in the park, and bringing areas back up to standard and adding new additions. They seem to be focused on the areas that need the the most work first. if these plans turn out correct and a coaster in 2023, I could then see them looking at the other part of arial park (the haunting, accelerator area) and then the pirate area and something new inside the pirate adventure building for 2024 and 2025 as part of their 5 year plan.
