It astounds me how many touring/GT race series are under the SRO umbrella:

Probably not with ACC, but sometime in the future I hope Kunos will keep the SRO license and keep adding series to its ever growing roster. Just imagine AC2 with all the road cars in AC, plus everything in ACC, plus GT4 and TCR
In the meantime, how feasible is it for Kunos to make the next DLC based on the old BPR series? They already have the F1 GTR. Imagine running that with 993 GT2, Venturi 600LM, F40 Competizione, Esprit GT1, Viper GTS-R, Lister Storm, Corvette C5-R. All faithfully recreated with ACC physics and sounds
