For me it´s rather easy, the car industry is in trouble all over the world and times are changing, also what some seem to forget that nowdays if there is any game dev that could get them to listen and relax their restrictions from the past, it´s Kaz, ranked as 24th most influential person within the car world if i remeber correctly.
Aslong as we get mechanical damage on all cars i would be happy, full on damage only on racecars sweet i´ll enjoy that too for what it is, another reminder to people is that there is alot of racing games out there yes but there is only one GT and the marketing power and weight it throws around both within the gaming world and automotive world is gigantic, none can compete really, they try but it´ll be a while more before they catch up.
They will deliver i´m certain of it, maybe not up to everyones combined standards as that would be a feat for the history books.
Sorry for the small rant but had to get it off my chest.
