DS1 officially discontinued

DENON has to make a new audio interface for DVS use, for 4 channels and SERATO compatibility. DENON shouldn’t discontinued the DS-1… RANE SL-4 (for SERATO use as well) it is a legacy product too… Do we have to wait for a new DENON DVS audio card or not? Anyone knows? Otherwise TRAKTOR Scratch is the only solution… Is it compatible with SC6000M?
