Well, he makes a good point. Everything must be considered in context. 86 million in isolation sounds great, but when you consider PS3 lost nearly half of PS2's marketshare, bled billions of dollars, and lost the 7th gen sales war, it's hard to see that as much of a success.
I mean, theoretically speaking, if Switch sold less than the 3DS lifetime and was a net financial loss it'd be hard to argue that as a real success story too.
From failure to flop there is a big gap. And SNES to N64 would be the greatest flop ever on his metrics (Sony was newcomer and took PS1 several years before really lightning up), then what would be WiiU 85% drop?
And as I said, we have to accept that the expectations and bar is held very very very high for Sony where a single system selling below 100M is all doom and gloom and others when doing over 30M are celebrated even if at the time they were much older companies in the field or much much much richer.
Also the loss on PS3 was a calculated move, they bet on BD using PS3 to win the race, which it did royally, but costing that division a lot of money they expected to recoup on other divisions that couldn't push the format alone. So we know it's disengeneous to put the financial loss on the calculated move of the HW as PS3 being a flop. Let's remember it had higher attach ratio than PS2, and saw more 1st party sales (from what I can remember) than PS2 as well. So from SW perspective they made more money from HW sold.
Xbox One goal was 200M https://stevivor.com/features/interviews/xbox-phil-spencer-brand-leadership/ (don't mind he thinking PS2 only sold 120M). So they reaching 1/4 of the target is a comparable flop?
Or would you preffer Yusuf Mehdi forecast of 400M to 1B Xbox One sold?? https://www.vg247.com/2013/05/24/xbox-one-microsoft-aims-for-1-billion-lifetime-sales-100-million-xbox-360-units/
People at Nintendo expecting WiiU to sell 100M http://fortune.com/2016/07/08/nintendo-wii-u-sales/
For N64 coming from the successfull SNES and having no name Playstation and limping Saturn as competition. Higgins, David (April 22, 1997). "Nintendo's black box hides a brilliant brain". The Australian. The Nintendo 64's simplicity is a key factor for projected sales of 50 million units over a decade-long product life cycle, according to Mr. Jim Foran, SGI's director of engineering for the project

Yes, only Playstation 3 is flop in context.
