If Corning does come out with this in the Next Gen. model of phones this could be a big thing, a good thing in extra protection, a clearer panel to Look through as Sapphire is one the most clearest and purist Crystals there is.. but it may make the price of the phone increase a little more than it has in the past.. I have a few Watches that uses the Sapphire Crystals in them they give the watch a more pretty appearance but the Trade off is... it pushes the watch to a higher price than say one with a Mineral Crystal or Hardlex Crystal..
Will be neat to see the Difference when they come out..
