I recall the higher fps option in last of us remastered on ps4 was just an unlocked framerate option. This meant it jumped around anywhere from 30-60. Was not ideal but TLOU had terrible control latency so an fps boost greatly improved quality of life there.
60 fps locked > 30 fps locked > unlocked fps of any description in the 1-60fps range, unless you're sporting gsync or freesync and aren't dropping below 40fps at any point.
Anyway, what the switch does with just 8W on a 720p screen in handheld mode is remarkable. Zelda for example has greatly responsive controls even at 25-30, and Mario odyssey is a dream.
Getting back to the thread topic, I think we've reached large diminishing returns when it comes to gpu power on 60hz, 4k displays. What the next consoles need is a beefy cpu to make those visuals shine at a higher frame rate. 60 fps should be the minimum goal because we won't be seeing high refresh rate, 4k low latency televisions any time soon outside of the enthusiast segment.
Any gpu at or close to 1080 base levels, and greatly increased cpu power (easy to do considering how slow the 2012-era jaguar is) would achieve this. However optical media is kind of tired, as it necessitates hard drive and internet access for frequent, huge updates anyway-so the optical drive just adds to the cost with little benefit. Some blu ray games you buy don't even work without a day one patch.
Solid State storage has gotten very affordable, very fast and will be more so going forward. So I envision games coming on sd cards, ranging from 32gb+ as standard. This means no more game installations, no more need for giant hard drives (also ads to cost). Instead if you want to go digital only, invest in a cheap 4tb portable hdd and plug it into the usb 3 port of your console. Alternatively if you want to buy games and collect them physically, have them on self contained storage like the switch.
If the ps5 and XBox One X2 (jeez, the title gore) go the route of just enough cpu for 30fps or inconsistent 60 with a focus on ever more 4k post processed visuals, internal storage, optical drives, game installs in a locked proprietary box that receives incremental upgrades every 3 years again...then I might as well stick with a custom PC build. May be more expensive initially, but I know I'll have guaranteed 60+fps there, and much cheaper games long term.
