6 Years. But it depends on the tech that's available. If the PS5 launched this year it probably wouldn't have been taking advantage of Zen2/Navi tech and been substantially less of a jump due to this, so 2020 seems like the best time.

Switch could be replaced in less than 6 years and I'd be happy. It'll be very outdated if it waits longer. Holiday 2022 for the successor is a good time imo.

About 6 years. 5 is fine too, but 6 seems just right.

I'm ready for the the next gen now. I've grown frustrated with long loading times and weak frame rates. As long as backwards compatible is always a thing, I won't mind adding to my backlog (I'll tackle it when I retire). Storage is also something I would like to see addressed, but it won't be. New tech is always exciting for me, but not weak ass new tech.

Can't vote on this one, my attitude has changed from generation to generation.

Mid Gen consoles seem to be the norm now. Expect PS5.5 and Scarlet 1.5 will come through 2024.

I'm confident that lifespans will one day become obsolete because of what will soon be the modular console.
It's been the direction consoles have taken since the original 'box (arguably well before that) to emulate pc's.
I think it's going to be very soon, even the generation after this, that consoles become fully customizable.

Considering cyberpunk 2077 will likely be the one pushing the boundaries on ps4 i would say 7-8 years.

I think a new generation should start whenever the tech can offer a generational leap at a reasonable price.

Thats the thing, people shouldn't ignore the costs of consoles.
Having to fork out 400$-500$ every 4-5 years will still be a decent amount for alot of people.

I think alot of people that buy a console, expect 6-7years from them (and even longer support).

Ontop of that with developement times of games, being so long now, it just doesnt make sense.

I think 7-8 years with a mid-gen refresh works out wonderfully.
