We should be seeing activity on steam DB by now relating to a new DLC but there is none. They would have started working on the next DLC right after Ghostbusters. But the game still feels incomplete to me. There are still rides missing like a giant splash flume with steep drops, a Gravitron, a Rockin' Tug, Thunder Bobs, Sky Swing, Slingshot, and more. I think Frontier is moving on to Planet Zoo and leaving Planet Coaster behind.
