If you have no interest in the board, why do you have so much interest in the caps? Can't you just buy caps that fit what you want instead of asking for something that seems like an odd move from a keyboard company that wants to promote one of their new products? Seriously, if they're gonna advertise PBT caps as a feature of the board, why would they take that feature and sell it as a separate product? Pretty sure they'd rather people buy the whole keyboard.
Anyway, has anyone managed to find some info on when these will be available in the US? Or knows of someone in Korea who would be willing to do a deal (seeing as how the website only ships to South Korean adresses apparently)?
