NS now sixth of all time and could be fifth within a week or two, the consolidation of both home and portable userbases still leaves a lot of potential sales even as we enter into its fifth year, the next investors report will be an interesting one.

Barring Nintendo doing the dumbest thing since the Wii U and replacing Switch this year, then yes, passing PS4 and Gameboy in 2022 is basically guaranteed.

One could also immediately post the next one.

I wonder if we ever need one where Switch knocks on the door of the PS2.

Unless they keep producing and selling Switch for 12+ years like Sony did with PS2, or their next system tanks out of the gate like PS3 did for PS2, or a huge amount buy Switch's for non-gaming purposes like tens of millions bought PS2 to be the cheapest dvd player they could find did, then it will never be a fair comparison. Switch will probably produce and sell devices 4-5 less years than PS2, will probably be followed by something with an attractive price point out of the gate (unlike PS3), and is used exclusively for gaming.

Because of this, I'm a lot more impressed by Switch selling 10 devices than PS2 selling 10 devices. If Switch we're to actually catch PS2 lifetime sales despite ps2's advantages, then in reality it will be much more impressive, not barely, than the ps2's success.

It might also come down to how well Nintendo is able to expand in developing countries. They have made some big strides with Switch but there is a lot of areas they could still build upon that and could allow them to sell for a long time.

Are this week’s numbers also going to be delayed like last weeks? I’m eager to see the final end of year numbers

12 years isn't really needed to catch the PS2 as 20m this year and next puts its well with in range of PS2 to the point even below average sales can catch it all Nintendo needs to do is to keep Switch active, if anything only another 3 or so years is needed.

Do you have any idea when the shortage will be over for PS5 and XS ?

Not anytime soon; though nobody knows for sure, many analysts predict it will continue throughout much of 2022 and perhaps even into 2023.
