well, of course it would have been great of them to use sapphire glass
my current watch has it and while the stainless steel case is scratched, there is not a single mark on the glass
but Motorola never stated that the 360 would get sapphire glass
but as you said, there is still hope and even if we end up with Gorilla Glass, I'm pretty sure that will keep up better than LGs plastic (!) OLED screen...
