Reply to Next generation traktor controller?

Is it possible NI might be working on a new S4-like controller (it's already been out almost two years) in the near future or will they just continue riding the success of the S4/S2 and release small units like the F1 to accompany their S4/S2?

Ideally, I'm looking for a controller with functionality similar to the VCI-380 and Twitch, but 4-channel and with actual traktor integration, so preferably by NI. Anyone believe this might be up NI's alley?
