This makes sense, as it would allow to release the console edition with all the DLC without Frontier having to worry about updating it.
The console version is launching with the base game animals (including Black and White Ruffed Lemur and Red Deer, but not yet Collared Peccary, which will follow later), plus the three animals that were the Deluxe upgrade on PC as a pre-order bonus. There is also a console Deluxe version that is the above plus the content of the Southeast Asia and Wetlands animal packs. The Deluxe version can also be purchased with a Season Pass to cover the remaining already-released PC DLCs, which states they will all be added for Console by March 2025.
As regards the PC version, the recent Frontier livestream contained the following exchange:
"I think some of our community might be worried that this could mean the end for Planet Zoo PC?"
"Yes, we've seen a lot of comments about this; can't say too much right now, but, I don't think we are quite done yet with PC."
"There you go."
"That's all I'll say."
"That's pozzy vibes, we like it, feel good about it, we don't have anything to announce but we think you'll still be happy with us!"
"Yeah!"
This only really allows two possibilities - one more DLC they think will be popular, or more than one DLC still ahead of us (basically dependent on how literally we take the 'quite'

).
I'll assume one good one and any more is a bonus. Both Frontier's previous park sims (Planet Coaster and the original Jurassic World Evolution) ended with a slightly fancier and pricier DLC so if we see that at the next announcement then I think the message will be received. Until then, at least we know something is coming.
