Yes, it's hard to see the future. KS might have just been "seduced" by the opportunity to make an official Blancpain game. It could have been an ego decision, rather than a sound strategic decision.
But on the other hand, a common complaint about AC was that not many of the cars belonged together. It was a real hotch potch of disparate cars, that didn't really belong together in a series, racing together.
Overall, I'm still optimistic about ACC. I really want to see more of a racing
simulator, as opposed to a driving
simulator. It might help that I don't mind GT3 cars
