Well, that's got to be true. Something has to say spec a, b, or c upon loading games now, moving forward. They already have to tell it version b is capable of HDR, etc. This all makes sense.Regardless of what they say, there will be software or hardware needed to comb through and deal with the differences between the two hardwares just as DirectX does with PC hardware.
I thought you were talking emulation, which doesn't seem to be the case. My bad.
