I disagree, 4k60 will be the new standard this coming generation. It will be targeted by developers, because Microsoft and Sony will demand their first party studios meet or exceed that requirement. Third party studios will appear lazy if they can't reach those numbers, so they will either remove features, or optimize their code to meet it.
And about Control: It was not really AAA title (I know you never said it was, but you gave it as an example). It's budget was 30 million and it's development time was 3 years. That's pretty good for Remedy entertainment that has 250+ people in its staff, and they did great with the resources that they had, but it's not really a triple-A title for our times. More money was probably needed to optimize the code and really polish the game, but you can't say they didn't do a great job. They were ambitious and they made use of the latest graphic card technologies (RTX), so I'm gonna go ahead a presume that you understand that one's first attempt at a type of work, is never your best.
Every gen there's expectation for 60fps - and every gen vast majority of titles are not 60fps. That's the first thing that goes out of window for most devs when they start pushing limits.
The way I see it Control is good looking game, but devs will aim much higher - and those consoles don't have enough juice even for 4K30 for type of visuals I'm expecting in next gen.
Going back to often misused and abused FLOPS - in 7th to 8th gen, PS4 had some 8-9x more than PS360 - that's without taking into account architectural improvements - and all that with 2.25x more pixels over 7th gen. These 9th gen consoles...they're barely managing to get to same numbers, and that's with architectural improvements taken into account, and they're suposed to deal with 4x more pixels than 8th gen.
So yeah, I fully expect most AAA will not even be native 4K (expect early in the cycle), if they want to really wow their audience. Variable resolution, sure, fixed native 4K, not so much.
