Yes, but the game must be developed independently for both if the gap is too big, I thought I clarified that to you when I quoted the japanese dev, and you also know that apps can only be supported up to a certain version of smartphones unless they are upgraded. As the gap gets greater, so does the ability of software to stay compatible on all machines.
Anyway, here is the quote I was looking for: https://gamrconnect.vgchartz.com/post.php?id=6022102
Last slide here: https://www.nintendo.co.jp/ir/en/events/130131/05.html
I get what you're saying, but even with a full generational leap, cross-gen game development is already standard practice during transitions. We'll see tons of games over the next year that run on both PS4/Xbone and PS5/XSX.
From Nintendo's perspective, all they need to do is make Switch software, NNID, etc carry over seamlessly to Switch 2.
I think we will just have to agree to disagree for now. At this time I just don't feel there's enough evidence to say with any confidence that their plan is to adopt the smartphone model.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
