I think what's more important is what hasn't been shown. Gameplay is notoriously absent. That, to me, tells the physics engine is what they're having issues with.
And that worries me, a fundamental system that's still so deep in the development it's not being publicly shown so late in development.
I hope they can get things working by next year, but I've heard this song way too many times. I don't expect 2023 release unless we get a video with the new physics...
