I was thinking of possible Switch revision systems, and one I hadn't really considered before popped into my head. A 2 screened Nintendo handheld much in the same design as a N3DSXL, perhaps slightly larger, though, the screens would still ultimately be a bit smaller than that of the Switch's. With 2 proper circle pads instead of the right one being a c-nub. This system like the original DS and DSlite would have 2 game card slots, one that could accept 3DS and DS game cards, and one that accepts Switch game cards, making it essentially 2 systems in one. Hell, optionally on the sides, they could have rails for you to put joy cons in if you'd prefer to use proper joysticks in portable mode (granted this would make it a bit wide this way, but it would be a nice alternative option, and I don't see why it still couldn't output to your TV if the proper plug were connected to the usb-c output. Maybe it could even output the 3DS/DS games to your TV when connected that way as well, if they went the extra steps to make that possible. I dunno, just a thought, such a thing would certainly be costly, but it'd be pretty cool I think, and I do really like how the DS series effectively protects its screens and face buttons with the clamshell design, and it would be nice to see that feature continue in some form on a Switch revision.
