It's the law of 3, and PS5 doesn't fit. Every third generation is a screw up, because enough time has passed for the company to forget their last screw up and they think they can dictate to the consumer.
Nintendo: N64 was the screw up, they let Sony in the door because they were full of bravado and thought they would always be at the top no matter what. GC was just more suffering as a result. Wii put them back but then the next third generation hit and Wii U is the result.
Sega: Genesis wasn't the first, but in many ways it was Sega's first real success. Dreamcast was the 3rd gen after genesis and well we know the result. They were never dominant in any generation but they still suffered the law of 3.
Sony: I don't really need to say anything about PS3 we don't already know.
MS: Xb og, a hopeful start. 360 an amazing expansion. 3rd gen Xbox, hubris and arrogance leads to several terrible decisions, Xb one failing to establish dominance even in 360's strongest markets, markets it ended up being the top console of the generation despite how amazingly Wii sold.
PS5 is not the fail generation where Sony makes terrible anti-consumer decisions, because it won't have been long enough for Sony to forget the PS3 early years and how much it alienated what Sony thought was a secure player base. PS6 would be the fail generation, but I don't think traditional consoles will be around by then so it's unlikely Sony or MS will get the chance to fail in hardware again.
