I expect it to last forever, and forever gone retro games forever unaffordable unless we are talking 8-bit multi-carts in that case plenty of games to play, in my backlog, I have literally 450+ 8 bit homebrew games on one like new cartridge that have like 10+ difficult levels of gameplay a piece, I never beat.
PS1, N64, GameCube, PS2, PS3, I don't will ever come down unless they let you keep modern games instead of renting them out for 60USD a pop, plus 100GB on a 600GB harddrive console, your luckly to hold and play 10 games at a time on a PS4, I'm sure the PS5 will be the same way too. AND the Xbox One Seies X. Same way. I could care less about 4k graphics I just want a console that can hold more then 100 games at a time on it's harddrive, that's reallly not much to ask considering Modern technology, it would seem technology has only gotten worse not better as time went on.
What is the differnece between a 4k TV and a supped up CRT with HDMI?
