A recent post on the PlayStation Blog revealed the R&D and hardware iterations that went into the development of PSVR 2, and it's been confirmed that one prototype used the PlayStation 4 controller's rumble motor.

It now comes to light that the earliest iterations of this feature saw mechanical design engineers using rumble motors from the DualShock 4 to make it happen.
