Well, it seems from what I've read so far that there'll be likely very few driver changes for 2016.
I've read that Audi has said it will not change any drivers, or maybe that was BMW?
Anyway, one change there could be is Robert Kubica.
In this Autosport piece it says DTM is a possibility:

Though in this week's paper magazine it says DTM is almost a certainty.
Any thoughts, rumours etc. for DTM 2016?
