Witcher 3 isn't coming out for the ps3 obviously (its ~8 years old). My argument is that nividia's "next gen fur tech" isn't exclusive to nividia hardware. They would be very stupid to limit themselves to only high end pcs in terms of their tech (from a money making standpoint. warframe is an example) as they have already demonstrated. I bet CD Project red is/will be able to implement nividias physX on ps4 and maybe xbox one given the caliber of people they have hired in the past. Vector math and massively parallel computing isn't quite as specialized as is once was.
