Switch had a lead of ~6m over the PS4 through the first 36 months, so the often cited advantage of the PS4 in Europe has been more than offset by other regions.
So did the Wii but that didn't matter in the end.
Did Switch not fall behind at the end of this quarter though? (Yes I know PS4 had one more Christmas on it but still)
Also to Slownenberg's credit Sony does dominate Europe and the Switch staying power still lingers in a lot of peoples minds.
We have no idea how next gen consoles will affect the sales of the Switch (Especially with Nintendo not having anymore Directs this year and very little 1st party games this fall)
or even if Switch can dominate a region like PS4 has in its 6th year on the market. Their "home console" support at times tapers off after 5 years or so.
What if they're forced to make a new "Switch 2" in order to continue getting 3rd party ports next gen? Surely that will get cut into sales and fragment the install base as well.
It's definitely not cut and dry that Switch will pass PS4 at all.
