Reply to USB turntables

Hello,
I wonder why nobody mentioned usb turntables yet. As far as I know there are currently 2 of them:
Vestax Guber CM-02 and CM-01 USB - unfortunately in japanese
Sony PS-LX300USB
Generaly there are made for ripping your vinyls into mp3 format, but what about DJ's ? I believe that there will be some drivers made by programmers which will make those devices more "Traktor - friendly" or maybe even transform them into final scratch like devices. Anyway we have to wait for more powerful devices because those two look like they would break after few seconds of scratching
