Actually yes, to be fair, there’s no info here that these are release months for players, rather just part of the R&D cycle (“As these initiatives are heavily R&D‑driven, timelines and scope may change depending on development progress”), in January these systems can easily still remain WIP or under testing/QA.
We only have info about the release of the first major update in April, and that’s the only thing we can rely on in terms of public announcements.
