How will screen protectors work for iPhone 6 and 6+?

Since the new iPhone 6 and 6+ have curved edges around the perimeter of the screen, how would screen protectors be made for them? I wonder if tempered-glass screen protectors will come with similarly curved edges that fit perfectly over the original screen and the edges? Even with the new "ion-strengthened" glass, I suspect that the screen would still be somewhat susceptible to scratches...
