He's a pc gamer, i am too and i understand his views. Otherwise i agree with you that, for consoles, its better to hang on to 30fps to enable a larger leap in visual fidelity. If you want higher fps then you need more capable hardware. He shouldn't be bothered by 30fps on consoles though, it wont even affect him right. He even noted he doesnt play console games so much. He will be able to play them at 60fps since he's on pc.
Not it matters, things are set in stone, 30fps is what the consoles get when the aim is high fidelity graphics. And sometimes, atleast in exclusives, you have options for lesser graphics in return for higher framerates.
IF that would happen, it seems 30fps is the target for 'next generation graphics' for consoles (if UE5 demos are anything to go by). Also, not always true that pc versions scale badly. Sometimes, and in special modern games scale quite nicely, from default (console) to high and ultra can make for some nice extra fidelity, in special when considering ray tracing. Look at Cp2077 for example.
Could have alot to do with expectations. Many had them too high and the hype was all around 30fps being the past, in special due to 'real cpu's' this time. Neither that or native 4k is what we can expect if we want this next generational graphics (whatever that means).
