What a lot of people don't understand is how hard it is to properly utilise multiple cores. Next-gen is not gonna change that significantly, because we can already see a best practices example of CPU threading: Doom Eternal. Plus, CPU requirements would have to sky-rocket so much in order for 60 fps targets to be hard to achieve on <8c/16t CPUs, it would be unbelievable.
This 'next-gen's gonna have 8c/16t zen 2 so non-8c/16t are gonna struggle' narrative is mostly based on ignorance. For a 60 fps target it will be meaningless, and even 4c/8t CPUs like 3300x will rock it easily. The real differentiator for CPUs is vis-a-vis >120 fps gaming and for those kind of games they focus on reducing the CPU requirements as much as possible in order to enlarge the possible playerbase & the scaling for extra cores isn't good anyway. That's why you see new esports titles like Valorant come out and try to push the PC reqs as low as possible rather than to go crazy on game design based on extra CPU. And for AAA it's a non-starter anyway, because they're so GPU bound they'll be lucky to have even 60 fps to play with - but really, it applies for PCs too.
The mythical game where an 8c/16t Zen 2 CPU is gonna get pushed to its limits @ 60 fps is just that - a myth. Just like with SSDs people don't understand CPUs either - it's about thresholds aka how much do you need, and the extra is wasted. There's no easy solution like for GPUs where you can just increase resolution and make use of more grunt.
For games anyway, if you want to run Blender on the other hand, well... sure.
