Did they prove to you that it worked well on the PS4 base? I mean lets not forget that an Operating System is an operating system. If every game on PS4 worked with PS2 Operating systems, they would say it did correct? They wouldnt advertise that it ran super well on it. But they would slap the ps2 logo on it im sure.
I mean did anyone run out and buy a Base PS4 based on the advertising alone? Did they really sell that aspect of it so enticingly that you couldnt resist the urge?
