The thing with Planet Zoo and Frontier is their very tight in their information they release unless someone leaked confidential info.
They are mysterious when it comes to releasing DLCS, before Eurasia you would probably know when theirs a new dlc as theirs a livestream but now with all of those community managers gone we now have elite dangerous workers telling us sneak peeks

Frontier is not predictable at all with the closest thing for us predicting is how they launch a dlc every 3 months that's it but now that's changed now that console ruined the schedule.
I don't think Planet zoo will be ending in fiscal year 2025 as that will hurting their cash inflow unless that game is planet coaster 2, but thats not happening as Planet Coaster 2 is probably releasing Fiscal 2026 or Fiscal 2027. If planet coaster 2 releases in this fiscals year then planet zoo is doomed and this is our last pack.
