they haven’t announced everything in 1.16 yet. Also, 1.14 was horrible performance wise. If it takes a few months to improve that, then so be it. A delayed game is eventually good, but a rushed game is forever bad, like the old saying goes.
there are other things you can do in the mean time anyways. Try out some mods, theres some pretty good ones out there. Alot of them have feature bloat and power creep, which i feel you’d be a fan of.
