LuckyBoyAK I'm not Justin and I'm not privy to any secret information but my guess like most other previous releases is that Justin has not included timelines for major updates intentionally and even for minor ones he has occasionally mentioned like "at the end of the month" or something along those lines.
RPG in a Box 2.0 is a massive overhaul to the engine as it's being migrated from Godot 3.x to Godot 4.x. This process, as posted above, is involving Justin learning Godot 4.x in order to add new features and make sure existing features don't break. Presumably this will take a long time and while it's in the early stages, Justin himself might not even know when it will be in a state to release to all of us eager users.
Additionally, IMO, giving timelines to the community is a double edge sword. It puts artificial pressure on himself to possibly cut corners just to deliver on time and if he doesn't and has to delay, there's going to be backlash.
Trust me, I want to know too but I'd much rather have a working, well developed 2.0 that takes a year or two than something rushed and broken just to quench the thirst of the community.
