There is some chatter about using the expansion port to add a 3rd party colour camera to get over this, but I wouldn't hold my breath for it.
Edit: I stand corrected, there is such a 3rd party camera linked on the page!
The official product page above has a link to one you can already preorder: https://arcturus.vision/
> Four high-resolution, monochrome cameras provide controller and headset tracking
(Emphasis mine)
So it's not really suitable for real AR out of the box. Thanks for the heads up!
