yeah, yeah probably. AVP uses less hardcore displays and accompanying optics. Fundamentally they're fancier Apple Watch displays, though it has more by mass. The front-back aligned polarizers for VR pancakes might be a bit complicated, but the lenses itself are rotationally symmetric. This one uses LCoS which will require front illumination combiner prisms, and also the big flat lens thing is probably built using lithography of some kind. I reckon it might not be holographic but something equally exotic like strategically laid out micro wedges suspended in the transparent stuff.

The earlier Meta prototype was quoted on media articles as costing over $10k or something and used transparent SiC for lenses, and they said work is ongoing to find a cheaper material. I don't think they meant the lens cost $9.75k and the rest $0.25k by that.
