Eh, I'd class the Scorpio and the Neo as the same deal. .5 gen consoles. The relative power difference between a Scorpio and a Neo (as per leaks) is the same as the relative power difference between a PS4 and an XBO (~45% in pure FLOP terms), and you wouldn't say the PS4 is in a different gen than the XBO, and neither would I for the Scorpio vs Neo.

From the leaks/rumors we have now, all games made for PS4 have to be compatible with Neo and vice versa, its likely that Microsoft will have a similar policy. If that is the case than power is no excuse for 3rd parties to exclude NX if it is somewhere around XBO/PS4 level of power.

A 5x power leap over a predacessor is pretty much a generational leap, doesn't matter where the Neo factors in, XB1 to XB2 leap if it is 6 TF will be 5x, not including possible things like a Zen CPU and maybe even HBM RAM. 

I think it's more likely they won't even bother, specifically the Western developers. No one wants to make like 6 different versions of every game, and Sony/MS are gaurunteed support first and foremost quite frankly because they do deserve it (they have a proven audience base that will buy Western 3rd party games). 

I just don't see Nintendo being much of a priority at all for developers, Sony/MS are basically shutting Nintendo out of the traditional market by having this much hardware all at once. 

The other problem is Nintendo fans hold a bit of a double standard here in that they feel they should get equal quality games to the PS4/XB1 even probably Neo/Scorpio, in other words they won't buy the NX version of a third party game if it runs better on another platform, we saw that with the Wii U with third party titles being shunned because they ran a whopping 5 fps slower or were a few months late or whatever. 

Those initial ports will then likely bomb which will then lead to the developer throwing up their hands and saying "well we tried, but NX doesn't work for us", it's a fairly predictable movie by this point. 

If thats the case than power doesn't matter, which was my point.

Well I mean if this was a "normal" console cycle, and the NX was going to be "a little better" than PS4/XB1 for a few years ... then yeah they probably would've gotten some support. 

As it is now though ... that's probably going to be tough. Neo/Scorpio + VR really muddy the waters and give 3rd parties too many other things to prioritize. 

Yep on that point you would be correct. But seeing that doing a PS4Neo and X1Scorpio version would only need a small scale down to fit on compatible PS4 and X1 instead of a compleate new version to run on NX that could make it a difficult step for NX. And from Iwata talk some months ago there is even the possibility that NX is weaker than PS4, and the difference is that it's a lot harder to ignore the market leader that puts a lot of 3rd party sales than to the newcomer from a platform that struggles to sell 3rd party.

Right now there's no need to speculate so much on what will happen because there's just not enough information known about what NX is! We know that Sony and Microsoft will always come out will more powerful versions of their current consoles because they've been doing this since the 6th generation. The added NX abilities is where things could get interesting. If Nintendo can fully capitalize on their SCD patent, they have nothing to worry about other than driving the base units install numbers...

wouldnt that same hold true if NX were as powerful as Neo/Scorpio?

Simple scale up/down from/to PS4/XBO & Neo/Scorpio being compared to completely new version for NX.

You were saying that NX being less powerful than Neo/Scorpio would be a problem for 3rd parties but are now agreeing that 3rd parties likely wont give strong support regardless so power really is not the issue.

I have serious concerns about the NX and it's chances of being successful, but none of them are really tied to Neo or Scorpio.
