Not a clue I'm afraid, though as it doesn't allow offline saving I imagine that they would both be online-only.
That's interesting. I guess it makes sense since they want to encourage brand loyalty, to make the series more interesting. They have been telling us to choose our manufacturer since that trailer came out months ago after all
Do all the brands have Gr. 3 and Gr. 4 cars? Or at least all the brands listed? Because if not it would seem silly to have some manufacturers eligible for more events than others. As far as Gr. 1 is concerned I'll assume they're not involved, for the sake of logic. There's also the fact that they probably won't allow us to swap manufacturer once DLC cars arrive, so that could end up having a lot of unforeseen consequences.
Good point, I'd like to know what the initial mileage exchange lineup is going to be. I'll probably end up regretting not grinding the beta up to the credit/mileage accumulation limits.
