The losses from the PS3 wiped out the profits from the PS1 and PS2. Even at $599 they were still losing money per console sold. Sure this generation Microsoft wasn't willing to lose money per console, but they certainly did for the OG Xbox and Xbox 360. Microsoft was nearly giving up on Xbox this generation until Phil Spencer convinced the current CEO of MS the importance of the brand and he was then given the money to acquire so many studios.
Sony always started the gen selling for a loss even on PS4. To break even they needed a retail game and PS+ sub. And Sony knows that they make the money on the SW and subs so losing 100 on the start of the gen and ensuring more profit later is their choice. They were even direct on PS4 that their objective was to accelerate sales. They didn`t cut the PS4 price a second time because the sales curve was already fantastic, but expect PS5 to be priced agressively.

Mr Puggsly: "Hehe, I said good profit. You said big profit. Frankly, not losing money is what I meant by good. Don't get hung up on semantics"
Azzanation: "PS5 wouldn't sold out at launch without scalpers."
