Recent rumours about ETCC 2017 also indeicate that Hungaroring, Slovakia Ring, Nurburgring and Vila Real should stay on WTCC 2017 calendar as well. (BTW, ETCC is about to be renamed into the European Touring Car Championship).
I wonder what is going to happen to France and Paul Ricard now with Citroen leaving.
