you do NOT want to open that can of worms here. trust me LOL. I do agree their web site is very confusing and seemingly not well put together.
OLED yes, someone said a later version of whats in the AVP but I can't verify. Not see through, web site claims to have pass through, which I think is probable, but we have no clue on the quality of it, no one really knows, product has not shipped. I imagine it will NOT have foveated rendering as the AVP does, or at least not as aggressive because a) cost, and b) causes some interesting artifacts with detailed virtual screens on the side.
