The only thing I could think they could possibly tease on the stream is hinting at when the pack will be announced. I definitely can't see them saying anything about one of the new animals or the theme of the pack, but I could see them saying something at the end of the stream like "so that's all we have for showcasing the console version of Planet Zoo we can't wait to see what all of you build in the next few weeks, and
make sure to keep your eyes out everyone on our socials in the next couple weeks, maybe this isn't the only thing we've been working on who knows?
"
Proceeds to release bug fixes.
We kind of know there's no new DLC till May now with the steamDB. I could imagine them maybe saying something in the April livestream
I'm guessing they're covering the Season Pass in decent depth. With the name, and the price being more expensive than base game, people have taken one look and said "
that is disgusting", without seeing that it's just a bundle with a known amount of stuff.
Technically it doesn't give you the DLC, it just makes the DLC free, but you still have to "buy" it, which is a very weird way to go about it. (On PS5 anyway)
