Well we still don’t quite known what the new Traktor piece of gear is but judging by the video it appears to be a 2-channel mixer with a row of push button effects. This seems to be targeting the CDJ/Turntable crowd. It could possibly be a dedicated mixer when not connected to the software?
As details are still a bit scarce we can only speculate. However, one thing is for sure NI is doing major things, their teams get little sleep, and they are still in my opinion at the forefront of the DJ/Producer product game.
