I think a lot of people in this forum need to go back and read the numerous interviews people had with Kaz in the lead up to GT5 and GT6, because there were so many overblown promises made about them before they came out.
Remember Kaz harping on about the "built from the ground-up" AI in GT5? It was apparently aware of the all new penalty system and the consequences for crashing into each other, and would not line up and follow each other. It turned out to be extremely slow AI that would slam on the brakes whenever the player was anywhere near them, making bump-drafts impossible, and overtakes as easy as pulling up alongside them, within a metre or so, and they'd slam the brakes on, even mid-straight, so you could sail by. They were also so afraid of overtakes that they'd just form a Trulli train and follow each other around every race, even if the car ahead was slower.
Remember the "built from the ground-up" tyre model in GT6? It was apparently built in collaboration with Yokohama, and was going to be a big leap forward for the series. It turned out to have no pressure model, very basic temp model, and the wear and performance was barely affected at all by the set up of the car. It was marginally better than the GT5 model at best, and still leagues behind their competitors.
Remember the revolutionary course creator that would be "coming soon" to GT6? It was "almost ready" for the game's launch, and was going to take GPS data from a mobile app to accurately re-create routes you had driven in real life in the game.
Even the damage in GT5 was pathetic after being talked up. They even showed the damage of the rally cars in trailers before the game came out, to make people think that's what the damage would be like for all the cars in the game, which is exactly what everyone here was expecting, and hyping up, until the game came out, and we saw the damage was pathetic on all but a small handful of rally cars. I even remember people claiming that damage was locked until you got to a specific driver level in the career, or until you unlocked the endurance races lol.
I think maybe just a "wait and see" approach would be best this time around, instead of the over-hype that every upcoming GT game gets every time here. People are bound to be disappointed once again, because as with GT5 and GT6, so many here let their imaginations run wild and their expectations get out of hand. If something hasn't been shown, don't expect it to be in the game, or any good. History has shown us that PD only shows the very best bits of their upcoming games, and everything they talk about that isn't shown pre-release is half arsed.
