Nintendo announces the Switch 2 [video]

Arg, they make the screen look absolutely huge with that large front glass panel during most of the video and I was thinking to myself, nice! But then at the end they actually show how large the bezels are underneath the glass and it is quite disappointing. Someday we'll have modern smartphone like mini-bezels (a few mm at most) in our handheld gaming consoles, but I guess not yet.

Do we know if the aspect ratio is the same? Maybe they're demonstrating Switch 1 games that have a slightly different aspect ratio, but can be updated to fit the new screen in the future?

That's a new Mario Kart game they're showing on the screen, not the Switch 1 version.
