As construction on Apple and GT Advanced's sapphire manufacturing plant in Mesa, Arizona, progresses, the two companies are already looking at expanding their available space. According to AppleInsider, several companies in the area are currently bidding on a potential expansion, which would possibly allow GT Advanced to put out even greater quantities of sapphire for use in Apple's products. While it remains unclear just how Apple will use the sapphire, there have been several strong hints and equipment orders pointing towards sapphire displays for the upcoming iPhone 6.
