It does look like a new Mario Kart game. It IS about time. I wish they'd also release a new Animal Crossing, I love that franchise so much.
As for the Switch 2... I'm a little "meh" towards the fact that it's basically the same console again, only with much better specs (most likely, I know we haven't seen anything specific, but I guess it's safe bet). This just seems like such a PS4/PS5 Pro situation to me, lol. I guess I was hoping for another weird-looking new console coming from Nintendo's famous sense for innovation.
Ah well. If this one isn't too expensive (looking at you, PS5 Pro), I'll see if I can give this one a go. At least it's backward compatible with physical games, so I'll be able to play my beloved New Horizons on it from day one.
