They threw out the roadmap 2 years ago to stop threads like this from being made. There will be no update to it because there's no reason to have one if it just leads to this mess again.

The January 2023 thing IS the update. As in they expect the game to remain in early access for another 2 years from January 2023. Come back in February 2025 and you can complain if they've updated the timeframe or not.
