And by "fell for" you mean people took the statement "we believe in generations" to mean "we will not publish any more games for PS4 after the launch of PS5, despite having done so for three generations of consoles". DF's podcasts are too long for me so I don't know what DF said, but if they really think that then I extremely roll my eyes at them - like this.
The "we believe in generations" statement was made in a gamesindustry.biz interview and it was an answer to a question related to Microsoft's earlier statement that said "
Xbox Game Studios titles we release in the next couple of years will be available to play great on Series and One". This interview was made in late May 2020, meaning it was published
prior to later clarifications made by Microsoft.
So at the time the question was "are all SIE Studios games going to be available on PS4, which is what Microsoft is doing for the first 2 years?".
The answer to that was "No". Which became true because so far Returnal and Ratchet&Clank Rift Apart aren't coming to the PS4. We're still less than a year away from the PS5's launch, let alone 2 years, so Jim Ryan's answer was true.
Some people and certain media outlets focus a lot on Jim Ryan's "we believe in generations" sentence, forgetting that
in the very same interview he also said the following:
We have always felt that we had a responsibility to serve that [PS4] community for several years after the launch of PS5 and that it represented a huge business opportunity for us," Ryan says. "The numbers are quite straightforward. If you say in broad brush figures that we have a community of 100 million PS4 owners right now, and in the first couple of years... I don't know, somewhere between 15 and 25 million might migrate to PS5, that still leaves a huge number of people with PS4s.
Sony going cold turkey on the PS4 on November 2020 was never in their plans, and they never lied. The only thing people "fell for" was a made-up idea. They said their 2021-2022 games didn't have to run on both the 8th and 9th gen consoles, and some of those didn't.
That said, it seems in the last year they've been changing their plans on some games to bring them to the older console. This is probably related to COVID and the worldwide semiconductor shortage, which is preventing Sony from ramping up the PS5's production as much as they initially planned. From Jim Ryan's statements it looks like Sony initially planned the capability to put up to 25 million PS5 consoles in the hands of gamers by late 2022, but there's a good chance they won't be able to produce that many consoles until then.
It needs to be said that the semiconductor shortage isn't getting better, it's apparently getting worse. There are automotive assembly factories in my country closing down and putting thousands of employees on layoff because they're missing the infotainment and autopilot SoCs. There's word of Samsung delaying the production of the highly anticipated Galaxy S21 FE because they're not getting enough SoCs. I know from my job that Industrial IoT devices are suffering a lot from this shortage as well, as they're breaking supply deadlines left and right.
A big customer like Sony might have upper hand on getting the minimum contractual volume of ICs for assembly, but it could still mean they can't ramp up production.
At the same time, people are spending more time at home so they're investing more on home entertainment - videogames included. Not only are they putting less PS5 consoles in the hands of gamers than they hoped (lower total addressable market than anticipated), the PS4 users are willing to spend more money on games.
These seem to me like a valid reason to change their mind on a couple of games, though. I hope this decision doesn't hurt the PS5 versions in technical terms, but contrary to some devs' statements
I think it certainly can and it probably will. However, these are different times and to be honest I'm just glad we're getting excellent 1st parties throughout the console's first year, despite everything that's happened.
Being angry because all the people who couldn't and won't be able to buy a PS5 in 2020-2021 will still be able to enjoy some games on their PS4 is a very childish and petty way to think. That was never a valid point, and IIRC there's a tweet from Phill Spencer mocking a guy from saying that about xbox games.
