Pioneer just Announced the DJM-T1 (Click for the announcement!) a 2 Channel Traktor mixer, this is pretty much a mixer with built in Traktor Scratch, it even comes with Traktor Scratch Duo 2 software bundled together!
It has built in transport and effects section to control Traktor, (similar to the TTM57SL!) plus a new magnetic crossfader for the turntablists! (Not sure how well the xfader performs though)
