This could be fun, so all you have to do is say what you want (realistic) a park to receive for the next 5 years (2016, 2017, 2018, 2019, 2020)
I'll choose Michigan's Adventure...
2016 - Premier Rides Superman clone
2017 - Relocation/conversion of Vortex at CGA to a floorless
2018 - Planet/Camp Snoopy
2019 - Waterpark expansion
2020 - Drop tower (S&S or Intamin)
Your turn
