Man I hope either the Switch sells 162M+ or Sony for sure officially confirms the exact number of PS2 sold, cause if the Switch sells anywhere between 155M-161M, speculation will run rampant of if Switch is #1 or not. People calculated the maximum the PS2 could have sold is around 161.9M, so if the Switch outsells that, that'll essentially end all speculation on which is #1 all time.
However, when it comes to the general media, I wonder what number they'll use for the PS2. Some media outlets use the 155M figure, others the 158-159M figure, and now it seems like the big media outlets are pointing towards the 160M figure after what Jim Ryan said that even Wikipedia updated the PS2's total. Hopefully at least one of those things happen to end the speculation.
My personal opinion though is that the PS2 sold closer to 159M. I can't imagine the PS2 outselling it's prior FY where 4.3M consoles were sold especially when the PS2's last FY only lasted 9 months. Yea the PS2's sales trajectory was a bit more anomalous in its later years but I can't see it sell much more than it's prior FY.
