DDJ RB 2 Will pioneer realese 2nd upgraded controller

Hey! I was intrested if there are any leaks or information from pioneer about next buget controller. Its been a few years and i am looking for a buget controller. Currently i am in selection between sb2 and rb. Rb is probably a way to go becouse of the free rekordbox software, but there are some of features on sb2 that rb doesn't have. So it has been a few years and i think there should be an upgraded version of rb around the corner
