The controllers look much better than the ones for Quest 2.
The headband looks like an improvement for desktop gaming. But I bet it'll be uncomfortable to lean on that battery while watching films in bed.
They appear to be using Holocake 2 lenses, which they've previously referred to as too expensive for the common consumer (probably why they increased the price of Quest 2).
There's no light blocking gasket, so don't ditch the one with your Quest 2 or other device, unless you want to buy one separately.
It has eye tracking.
It's called Meta Quest Pro, rather than Quest 2 Pro.
There's a charging unit, which may mean there's no direct USB-C for the controllers.
