Still fresh, damnit!
For those who have never touched a sheet of PC, PC is very ductile, you can "cut" a 2 mm sheet of acrylic by marking it with a sharp tool and then bending, but if you try that with PC, it doesn't break, it just bends. PC's high impact capacity and clearness is why it's usually used for motorbike screens (windshields), car headlights, and any application which requires transparent impact protection (but not heat protection).
So if you drop your Pyra, its case will not break, but most likely it would dent.
My only personal experience of testing polycabonate parts to destruction is in breaking up old CD-Rs and DVD-RWs. Those are made out of layers so the individual thicknesses are even thinner than that of an optical data disc. They almost always delaminate when I bend them (inside a plastic bag in case of shards flying out), and then break at some point past 90 degrees from memory.
I think what's happening in that video is due to the impact compressing the metal there's quite a lot of heat generated. I've never known a cold drop to dent any kind of plastic I can think of, it'll either shatter or scuff as it rolls.
