Switch is pretty much alone in this generation & it's a runaway success but lately it seem like 3rd parties only want to port games over to it instead of making Switch games. PS5 will most likely meet the same fate unless it light a fire inside of devs & make them not even want to turn back to make games for order consoles.
Sony will basically have to convince companies to make PS5 games over making PS4/Xbox One games with enhancements.
no, what probably will happen is the same that happened between this and last generation, nintendo released WiiU at the end of the last generation, for a while they received ports from third party just like PS3 and 360, then PS4 and Xbox one replaced Ps3 and 360, thirdparty games were more and more scarce on Wiiu, but also because the console was not a success, then they released switch, this time around switch will probably receive more love from third parties when the next gen starts maybe not much in term of ports from next gen but minor games and ports from current gen will probably be released maybe even exclusives versions similar to marvel ultimate alliance 2(Wii and Ps2), switch will receive less and less thid party games as the generation progress and then nintendo will release their next console and hope is a success
basically nintendo consoles are half generation early(or late) its not necessarily a bad strategy as they can decide if taking a crazy idea that may be success(or not) without investing in powerful hardware or they can take the powerful hardware route with the time advantage and disadvantage = more powerful without much R&D but starting behind your rivals in market share very similar to what they tried with WiiU
in my opinion they will try a succesor of switch with a more powerful nvidia soc with a minor crazy idea,
my prediction is mini portable consoles that interacts with the bigger switch2( that may or may not be portable) for things like 2-4 players and some nintendo games made around that idea like one player controls bowser and the others mario, luigi, toad played in each mini console, also the mini consoles will download mini games or even nes,snes roms from the switch2 so it doesn't use cartridges but you can share with friends this mini games that cannot be shared further as the mini consoles can only be erased and loaded with games from a switch2 with a registered copy of the game, the switch2 will be marketed at parents/young adults and the mini consoles as an idea for kids so parents can play with their kids even send them messages over wifi and video chat, with no need of buying them a switch2 and kids can have mini games and nes/snes/gba maybe even ds and 3ds games(for mini consoles with 2 screen$$$), if it doesnt work you still have a more powerful switch2 maybe there will be nintendo kiosks so you can download games for a small price to you miniconsole that will last until you erase it and upload a new game or maybe last for just a few days like a rent service
we will see in 2-3 years if I was right
