Rumor- It seems that you have a cut scene when your a kid in the early 1960s and a mobster of Empire Bay, is on TV talking about LCN after a failed hit on him(Valachi comes to mind). You end up going to Vietnam, then back state side, where you hook up with your old friends on a hijacking job. That is the rumor and 2K has not confirmed it, but there is a lot of chatter with a voice actor asking questions ando let slip that there will be muscle cars in it, so late 1960s early 1970s which was a great period for the muscle cars.
