Little to no load times (depending on devs) I think that might be the best promise a console manufacturer has ever staked a new gen on. I find the 8k tag to be more of a push to avoid using native 4k as a promise while getting the thought in people minds that 4k will be a given. I still think there will be a few devs not pushing for full 4k next gen or at least early on so nice PR move without having to promise 4k and software not delivering. Love that they are keeping VR with support for the current HMD and hope this pushes the fools who haven't bought into it yet to go out right now and buy a headset.
8k doesn't mean anything for gaming. It's not feasible. But Netflix, sure.
