Why you ask?
Its quite simple really as seen in the interview the PS5 is build to be futureproof and has a solid predecessor in the PS4.
The XB4 in the other corner, is rumored to be weaker and doesnt have the same library and most games will be playable on pc anyway. Besides how strong will the brand be after the flipflop known as the XBO.
And then we have the NS a great console but so far behind the curve most tvs wont cater to its resolution in a few years. Doubtfull if even the NSpro will handle stable 1440p/60fps. And ofcourse half its sales have been made in the current gen.
Thus my expectation for next gen which will result saleswise in the order Ps5>xb4>nsw
Are you really going to separate Switch sales by proportion sold during this generation and the next generation? That's rather silly as it makes any sales comparison pointless.
The rest of your arguments are almost equally odd.
