Like what steam box or smart phone does, which is updated every year or two.
Say the first NX have 802.11ac, and the second has 802.11ad, 1g of more ram and a newer processor.
Say if their policies are better, would that make a difference?
And this time they must overpower ps5, which could potentially overpower some old hign end pcs. And about the innovative idea, this could be hologram(not hololens, and while everyone else is on vr or ar, nintendo could do something good, just think of hologram mario stages). Something tells me nvidia and intel might offer some thing good, and intel's advanced finger scanning (which stomp hololens) is just perfect. They also have wigig to solve the problem of using handheld as processors.
The 8th gen is more or less the generation of remaster the remastered games so the 9th really needs to be far better and if Nintendo makes their next home console slightly more powerful than a PS4 or much more, that is ideal, but they really need to have third party support. Wii U failed for numerous reasons and one of them being the lack of third party support.
