That's talking about a new DLC in Q4 2023 which obviously never happened.
On the official roadmap image it just states Ark Survival Ascended Surprise for Nov 2024. During ExtraLife last December Jeremy just referred to it as a surprise but that it was gameplay related. He then went on to say new canonical story DLCs will come after all ASE canonical maps are out, which would put it after Gen 2 in 2025.
So what you quoted is not necessarily related to the surprise.
@genie45 is this correct? https://ark.wiki.gg/wiki/ARK:_Survival_Ascended#Roadmap
On the roadmap on the Wiki it says:
New DLC - Currently Expected On November 2024
But on the official roadmap image it just says Ark Survival Ascended Surprise (didn't specify it being a DLC). All i'm aware we've been told is Jeremy said it is gameplay related.
So am curious if New DLC is correct or an error?
Why would they remove it? Aberration is underground and never sees daylight, therefore Megalosaurus wouldn't change. If they changed how it previously worked in ASE then it would pretty much make Megalosaurus useless.
