Corning Compares and Flaunts Gorilla Glass 3 to Sapphire Displays
Following Apple’s adoption of sapphire crystal as a strong and durable covering for the rear cameras on the iPhone 5 and fifth-generation iPod Touch last year, rumors of expanded uses for the material have gained some traction. Amid the discussions of the potential of sapphire, Corning published a feature outlining why its latest Gorilla Glass 3 is in fact already a better option than sapphire for mobile device displays, citing greater strength, lighter weight, less energy cost in production, and significantly lower pricing. The features are the reason why Gorilla Glass has seen widespread adoption, with Corning reporting that over 1.5 billion devices have been made with Gorilla Glass. According to the feature:
Jeffrey W. Evenson, [Corning] senior vice president, remarked, “Discussion seems to center around sapphire as an obvious solution for a cover material. What would people say if someone invented a cover that was about half the weight, used 99 percent less energy to make, provided brighter displays, and cost less than a tenth of sapphire? I think they’d say that sapphire was in real trouble. It so happens that we at Corning already invented that cover – and it’s called Gorilla Glass.” Evenson added that the company’s tests so far indicate Gorilla Glass requires about three times more force to break than sapphire after both materials have received similar wear and tear.

How does Corning know the Sapphire production and energy costs? Most likely it is a complete guess. When they quote a 99% reduction it makes me think they are delusional or have no math skills - either way a major credibility hit.
It's worth mentioning that the Gorilla Glass 3 didn't come out until this year so the iPhone 5 could not have used it. Samsung also chose a cheaper glass for the Galaxy Nexus.

So why would Apple go with Sapphire over Gorilla Glass or did I miss something here??

Didn't Corning fail to mention the main reason for using Sapphire? It's much more scratch resistant than Gorilla Glass. That's why it was used for the camera lens.
