'8K' is currently a technology designed to make very large screens at 'normal' viewing distances look appealing. On a smaller monitor screen it is far less attractive. Even if they scale it down to around 40", which some people now quite admire as a monitor size, it is completely overkill for a monitor. You would need to sit very close to the screen to actually appreciate the pixel density, save for the decreased need for anti-aliasing when gaming (perhaps not such a plus given how much GPU horsepower is required anyway). It isn't an attractive proposition with the scaling and GPU horsepower where it's at currently.
