It seems like a no-brainer to just make a better Switch, so I’m hoping for the same things as you. I really hope they see that the best thing they can do is the most “boring” thing: just make it more powerful. Give it maybe a better screen and more battery life. Maybe update the joycons (but still use the form factor because people have multiple joycons and wouldn’t it be nice to just use the things you already have?). But also let me play all my switch games. And maybe recent releases (uhh Zelda) could easily work on this system with better framerates.
Stuff like that is all I need. We tried the Wii, and it was fun for a time. The Wii U was interesting but obviously not the right choice. But the Switch idea is so excellent it just seems like they’d be fools to try and change it up significantly.
