This is a fully plausible scenario. I feel like it's a coin-toss now, but if we get word of a JWE3 release date or a PC2 DLC? I'm calling it.I agree. JWE2 last pack released earlier than usual for them to wrap up before Planet Coaster 2 launched later on in the year. I could see them wrapping DLCs for PZ early this year in anticipation of JWE3 later 2025 which we now know is still coming this year.
Based on what we know at the moment though, it would be a very odd pack to end on. But that doesn't mean they won't. Especially if this is more of a "gotta fill the space and keep bringing in revenue somehow" pack that wasn't part of the game's roadmap until last year, y'know?
