Lets get real about the most likely scenario with NS.

[Soundwave]

I agree with some of the points of the OP.

Switch isn't a great name, but it's not terrible either. It's kind of like GameCube ... it's just sorta ... "ok". NS rolls off the tounge fine too, I don't see why it doesn't and "NX" or "DS" does. Most importantly it's a clean break from the toxic "Wii" branding.

I think Western third party support will be wishy washy. Maybe like what the Wii U had for it's first two holiday seasons at best (some multiplats, while missing other ones). Japanese support will be good, maybe even better than the 3DS because it has some real horsepower to handle even high end games provided the dev is willing to downscale them some.

The home console exeperience that it offers is not likely to be great, it just doesn't have the horsepower there. Tegra X1/X2 are good chips but they don't stack up with even a XBox One S.

It will sell better than a Wii U because it's actually portable but I think it will be below the 3DS unless several things go right for Nintendo (ie: new hit breakthrough IP like Pokemon or Splatoon).
