Quest 3 Will Get Inside-Out Upper Body Tracking & AI Legs - lemm.ee

TL;DR: Quest 3 is getting inside-out upper body tracking, allowing it to track your wrists, elbows, shoulders, and torso. It will also receive AI-based leg estimation.

I wonder if that means games can use the direction your torso is facing for the walking direction in games. Neither hand based nor head based is a great solution currently. That would be really nice.
This is awesome if it tracks well!
