Apple is not aiming for a sub 1k device. They're aiming for a device that uses visionOS, that they can ramp up production for, and that non-enthusiasts might start to be interested in. XREAL or some other manufacturer can probably get into the simple tethered display market in the next few years, but Apple is not going to do that.
Eventually there will be competitors on the market that have displays comparable to what Apple has right now. Apple wants to have that superior software system experience locked in before everyone else has a chance to catch up with their superior hardware. A headset that is half the price of the pro version, can be rapidly scaled up in production, and is still better than any competitor on the market is possible with these 2.1inch micro-OLED panels. Wait for used versions of that device to trickle down if you really want a sub-$1k device.
