Once iphone 7 (2016) has gone thru a teardown (October??)
I would check in detail why "sunken" home button and "sunken" apple logo as shown on recent leak pictures.
I see no reason there will be "direct" revenue from Apple. LQMT (if involved) will be dying to give it away to Apple. Again, PPS for LQMT in the near term has nothing to do with revenue.
IF home button is indeed ultra low profile (hence sunken), it has to be liquid metal (I bet more on liquidmorphium) based......and it has to be output from an Engel machine.
