If... we don't know that, and i really doubt there is an exclusive for Thrustmaster or if others don't want to pay to sony, Fanatec said they will have PS4 compatibility with CSV2 base and a wheel with security chip inside, but we don't know nothing more for long time, since they made the announcement. We must know that there aren't to many wheel makers, Logitech quit, Mad Katz only on XOne, Thrustmaster on both, and Fanatec, but Fanatec not even pay for PS3 compatibility... they use the G25/27 driver...
I don't know if there are millions of gamers upset, i know they are a lot here and in some other places, but millions?
Most of people use DS to play.
It's business, and if a majority of company's do what we want, i bet most of them have closed.
