I forgot to add.
About the 8-inch screen rumor, someone here did a mockup, and there’s no way they can keep the same body size if the screen is 8 inches. The body would need to be bigger, as well as the joy-cons. This is like actual tablet territory. Switch is technically a “tablet” but it isn’t. It is smaller than most tablets even the small size ones. My problem is that I don’t think the switch needs to be bigger. I also think Nintendo is fully aware of that. Switch era Nintendo is very mindful of design, particularly aesthetics. The switch is actually a very attractive piece of tech. They made design choices that trade certain ergonomics for looks. I don’t think this is even the right word. At first, I wanted to say "sacrifice" but I don’t think they did that either. It’s more of a middle ground trade for aesthetics. It’s comfortable enough to hold while still looking amazing. It doesn’t have a "d-pad" because the joy-cons need to work as separate controllers, but that also gives the console a strikingly symmetrical look. The thumb sticks are also positioned for the same reason, and they also feed into the aesthetics of the console. This time asymmetrically. The switch doesn't need to have a bunch of lumps and bumps on the back of the device because it isn’t needed. That would be atrocious.
In short, I can’t see them making a bigger, clunkier device. The steam deck tanked for a reason. The 8 inch screen and 512 gb memory all seem very fishy to me. "Plans" will keep changing methinks.
