Going off that video, PD themselves definitely did say those things. It's also perfectly possible however, that Sony put pressure on them.
The same can be said for Gran Turismo 4 on the PS2 though. I should know, I was playing it earlier. There's always been a noticeable difference between tarmac, gravel, and other surfaces on the game. My point was that no game has yet managed to succesfully emulate the feeling of real driving on a controller - and not previous GT titles lacking difference in feel between surfaces.
Sounds amazing, if they can pull it off. I'll be keeping my fingers crossed. 👍
I mean the GT7 info being said is by Sony.
You have to understand that Dualsense is very different to Dualshock.
Dualshock had two sets of vibration: strong and low, and used a couple of motors to achieve vibration.
Dualsense is far more sophisticated. It has voice coil actuators, which are far more precise and most importantly programmable. Rather than having two modes these actuators can vibrate to any sinusodal waveform, giving a greater texture feel.
