Maybe. But at least Samsung has made thinner phones, so there's a precedent.

My Samsung Wave with gorilla glass got scratched up pretty conspicuously when it fell out of my pocket while I was in the passenger seat of a car, down the right side, and under the seat. There were no hard or sharp metal edges anywhere, just that plastic carbon stuff and upholstery. It wasn't a fine line scratch, it was a smeared spotchy scratch, the worst kind. Don't trust those online scratch-proof videos. It is only RESISTANT, and that can mean anything.
