Based on the precedent set by the 1-year anniversary update for Planet Coaster, and the fact that such an update wouldn't preclude a final paid DLC before the year's end... I think we might get one. Maybe 3 "new"/unique animals along with 2-3 that are relatively new re-skins. Along with a new (relatively big) feature or two. And probably some scenery items, new foliage, etc. As far as features go, I'm thinking it doesn't need to be anything as complicated as adding aviaries or whatever. Something as simple as making more items re-colorable would add a
ton more flexibility to the game as far as creativity goes.
While an update like this would be "free" for those of us who already own the game, there's a potential financial benefit for releasing something for free if it's stuff that's big enough or requested enough that it will:
- Encourage more people to buy the game! This is an obvious one, and I can think of a few features and animals they could add that could bring more people in (e.g., meerkats and otters, penguins, seals or sea lions, some sort of aviary set)
- Keep content creators on Twitch and YouTube streaming content focused on the game (with every DLC most of the content creators have commented about the lack of animals and each seem to have a short list of features that could be added to really up the game's value)
- Keep your average player playing the game more, which would result in more paid DLC purchases down the line
I don't expect anything for free, and I'm completely willing to pay for whatever they release. But I really do think there's a financial rationale for them to release a free update with a significant amount of content. So it's "free" but in a loss leader sort of way...
If you release a relatively big, free update and announce that there's a final DLC coming in December? Then sales for that DLC will be up too, if people are feeling super positive about the game at that point, and if the DLC focuses on some of the new features added in that free update.
