Maybe they actually will....Well, it's time for them to finally add proper full BC allowing users to use user accounts from Switch (and if possible previous platforms) to access the digital games and savedata they had in previous platforms.
Ideally what I'd do is to allow users to link in Switch 2 their Nintendo user accounts they had from Switch, mobile, 3DS, DSiWare, WiiWare, virtual consoles and whatever else they had.Maybe they actually will....
After-all, last year they teamed up with, uhh.... DENA?.... to create a new join venture specifically tasked with creating a new Nintendo accounts system. The current one is garbage of course, so this was needed anyways, but when making it they could support things like digital libraries. It would also give people an incentive to actually buy digital over physical. Nintendo also, seemingly, has plans to "support" the Switch for years. So expect it to have a 3DS-like long and painful death.
For Switch, sure, assuming they use a similar form factor. For mobile, maybe, depending on touch screen capabilities. Problem with the rest of that is the Wii, Wii U, DS and 3DS titles would all need major control tweeks -often on a game by game basis- and might end up either unplayable or bad feeling. So yeah, I think it will just be Switch and Switch 2 with access to your mobile account data and if you're lucky some form of Pokemon Bank integration.Ideally what I'd do is to allow users to link in Switch 2 their Nintendo user accounts they had from Switch, mobile, 3DS, DSiWare, WiiWare and whatever else they had allowing you to download and play all the games you bought them on Switch 2, and also having some system to import your savedata from there.
Nintendo's working with nvidia for the switch successor, i reckon nvidia might share some dlss secret sauce with nintendo, cause right now fsr is good but nowhere near dlss.
