Just cause someone pointed me here, this board is using the same controller that other boards have been using to achieve that "full NKRO over USB." Though, not to stir the bush, but it's the "only 18KRO over USB" one.
There is no common "only 18KRO over USB" device that multiple keyboards are using - it's a myth!
Do you have any evidence to support the claim that it isn't really NKRO?
I'm inclined to agree with Ripster on the elementary level, that 18KRO = NKRO for all intents and purposes.
I agree with that too, on an elementary level. We do only have 10 fingers. Above 10KRO the only reason to be interested in the details is to see how compatible (with varied OS) the method will be - that's a lot more important than exactly how many KRO it supports. But, the exact KRO gives us a clue to what method is used.
Accurate marketing? Sorta.
They're not lying and they're not being deciteful so I don't think it's a case in which enthusiasts should care too much.
They would be lying though. Facts are facts. It's illegal in most places to sell stuff based on false claims - that's why the small print on e.g. NKRO Filcos: "NKRO over PS/2, USB limited to 6KRO" or similar, even though the banner says NKRO. If a keyboard didn't support NKRO over any interface, it would be false advertising to say NKRO anywhere on the advert!
