Going with NX here. the PS4k at the end of the day is just another PS4. So I dont expect to see any more than 30% more sales as compared to what it would usually be around that time of the year whenever it releases.
The NX however is a brand new console. And typically unless things go really bad it should be able to at least do 500k-1M first week. and that's even downplaying it being that the PS4/XB1 were able to do 1M day one.
If Nintendo can't at least manage 500k-1M first week then I fear they are in even graver trouble than it seems now.
