Pioneer DJ DDJ RZ & DDJ RX

Well once again Pioneer DJ has made a HUGE move in the dj gear world with there 2 new controllers exclusively for there new Rekordbox Dj s/w. How much of a bite will this take out of Serato's hold on the dj s/w market? And with DVS coming next year will Pioneer want to take over the Control Vinyl market as well? Only time will tell.
