If all gaming consoles and handhelds were still being produced and sold today, who'd be bought the most and how much would they sell for today?

Was kinda wondering like the question states

If game consoles and handhelds (from NES onwards) were still being produced and sold today, how much would they sell for and who's gonna keep selling like hotcakes

And Incase you're asking, no NEW games will be produced for these consoles but they'll still keep making physical cartridges and Discs for these consoles in this instance

There also won't be repairs or online updates, shops and maintences for the discontinued consoles like the PS3 an Xbox 360. Basically just imagine this timeline of sorts is "we're obligated to keep making the console and it's games to consumers if they want to, but we've moved on so we don't care about repairing the console or making new games or supporting it much at all anymore" unless it's something like homebrew/jailbreaking or indie devs deciding to make new games or custom updates for everyone

I feel like the Gameboy line as well as NES and Super Nintendo by todays standards and manufacturing would probably be cheap 10-20$ "toys" by this point

N64 & PS1 and onwards would basically be the only consoles worth grabbing for series gaming and basically until PS3 and Xbox 360 those console will be somewhere between 50 and 100 dollars

Then Xbox 360 and PS3 would be like 200-400 dollars due to their library, backwards compatibility and things like being used as a simple DVD player

I feel like the 3DS given it's modding scene and ability to play basically up to the 6th generation now, would sell sell sell. Maybe even the Vita as well but not as much. Any so many people would probably be buying a WiiU, PS3, Xbox 360 and PS2 based off backwards compatibility and homebrew/jailbroken consoles alone
