As the person that owns one of these, I can say (as per my review too) that USB 8200s are 2KRO. Cherry is cheap like that.
Oh, and after using it for a while, there are some weird cases of random keys not registering properly during typing. I can't tell if it's my typing (fine on the work G80-1800 with 4KRO) or a controller problem, as I can't replicate them reliably. The keys are fine individually too. Meh!
