I doubt very much if they will be changing any current generation of cards, the rgb 12v and 5v have been available long before the z490 series already. With the next generation of cards just a few months away they have no incentive to upgrade current gen's lighting features. Usually the motherboard headers are going to be for fans and lighting strips and other add on items like water blocks. Most likely any gpu with addressable lighting will come from the factory that way and not as an add-on i would imagine.
