Doesn't that leave pretty much tinted glass and carbon-titanium sapphire as the only options?
Well, then for me it's a 20:80 because of all the work in the background.
And, again, of course it can be pulled off. You pretty much only need to match the iPhones manufactured till presentation time, and that's never supposed to be a lot due to that East German marketing craze. That's like 15M/2. Piece of cake. And yes, I expect them to do a dual edition launch with an AR and screen protection upmark since the additional benefits are well worth it.
