In case anybody from NI is reading this forum .... do we need a new TDJ version for the updated S4 and s2 (announced today) ?? .. currently confusion is complete - both devices speak about Traktor Pro compatibility (Traktor pro 3 in Nov), what about (old) TDJ ? .. is a new version needed ? - the new S2 has an iOS port, the S4mk3 not .. and TDJ supported hardware (old S4 and S2) can not longer be ordered ? - or will TDJ not longer support any S4 (S2 only) ?? thanks for clarifying !
