1. PSneo sells well.
2. XB1 Scorpio sell well
3. NX sell well

#1 is the only one that's even somewhat reasonable.

MS is building 'gaming as a service'. If their PC store becomes successful Xbox basically is kind of a settopbox. In the end it's all about selling software, not where you sell it. So MS won't care if they sell 40% on Xbox and 60% on PC or 70 on Xbox and 30 on PC as long as they sell enough.

Nintendo, well, from where should those 200m come? If we believe the newest outings and rumours, NX is likely weak, will definitely be blue ocean and likely try to get the lost casuals back. The latter one just aint gonna happen, the middle one means Sony and MS don't even need to care and the first one, well, again no CoD, FIFA, Madden, GTA, AC... on NX so all those 'core' gamers would buy it as a secondary device at best.

Sony, well, if Neo doesn't sell, they'll keep PS4 as an entry level console anyway. Question isn't wha happens with PS4 but what happens afterwards. Playstation Mobile was a failure, Vita has been taken from life support and Playstation Now already looks like passing away. So chances for Sony to go the gaming as a service route don't look that good. But that's 2020's stuff.

All in all, Sony already has won this gen. NX won't do anything about it, even if it's going to be a success. Just because Nintendo isn't aiming at the same audience. MS is trying the gaming as a service route. Which is a risky approach. They might be successful as well or fail miserably. Again, nit the same audience. If anything MS has to wrestle with Steam and Sony at the same time.

Scorpio and Neo don't matter for the time being because in the short run they're both aiming to the 'high fidelity' console gamer.

At the moment it looks like Nintendo won't matter just because of a totally different audience. So sales of NX probably don't matter if we look at PS4/Neo and XBone/Scorpio.

Sony already won this gen, Xbox Scorpio starts a new generation. I wouldn't be surprised if Sony anounces ps5 next year with a holiday 2018 launch.

Please explain to all of us what you mean by better experience?

More games and more variety. VR also, for those who care. I worded it a bit badly, but still.

NX is going to win this "new" generation :)

You want to prove your point in more games and more variety? Also isnt Xbox One getting Occulus Rift support soon?

1 - MS get slowly and silently away from console business, it's more and more about "Windows 10 market and ecosystem", and the Xbox become some kind of low-mid tiers reference model. They are mildly successful. PC keeping the XBox alive, and the windows market place taking some shares thanks to the XBox. But they are a in both area (hardware and marketplace) losing to Playstation and Steam.
2 - The Nintendo NX flops hard, because they don't have a Wii like success, and didn't fix any of their problem (3rd party, hardware, HD game output, players outside the smaller and smaller Nintendo fan group)
3 - Neo and Scorpio do both relatively fine, but as mid-gen, expensive consoles with forced compatibility, it does not have so much impact, and are a niche market. As they become mainstream, Neo clearly takes the lead based on the advantage of PS4 compatibility.
4 - PS5 if any is kind of lonely, fails to create a significant impact with a PC like low-tiers hardware, and any competition. E3 for the same reasons is boring.
5 - The end ?
