As a kid who grew up in the 90s, my only question is how many bits will it have?
Seriously though, I expect it to be in the ballpark of the Steam Deck, just in a smaller form factor. I don't see Nintendo releasing something as ginourmous as a Legion Go, as much as I love that thing as a desktop replacement. You just can't call it really mobile anymore.
