Maybe I'm weird, but this Neo and Scorpio situation makes me think that it makes graphics, or rather, power difference within a certain reasonable distance even less relevant.
I'll even ignore NX's existence, we are going to get several levels of graphic fidelity at several different price ranges, kind of going up in a stair until you reach the "top" with the PC. Assuming developers aren't going to do Neo and Scorpio exclusives, all consoles will be within spitting distance visually for most of the consumers.
From an XB1 to a great PC, there isn't a potential difference that significant that makes an XB1 not viable, not marketable, not minimally desirable to the general market. A market that really doesn't notice all the FPS, AA, Vsync, ambient occlusion, techwizard black magic thingies that are going on and/or maybe doesn't care enough to shell out more money for that difference. I really don't think hardware power is playing a significant part in this "race" and it rarely, if ever, has before.
This isn't even comparable to the gulf between Wii and PS360 or even Wii U and PS4 and X1, the same games can run on all hardware and most people won't care for the difference. Baring exclusives, the games are and will be the same too.
Now let's assume NX is as capable as an X1, I'm assuming/hallucinating/hoping that NX gets reasonable 3rd party support in this argument, is this that offensive to graphical tastes or does this power difference alone make NX an impossible sell?
The question here is everything else. What it is, what it costs, how they market it, how do they get support, etc. These will determine success, even if some might personally need top of the line hardware.
