I also don't have a Switch 2 and probably won't get one till early next year, but for reveals, I can't think of much I'd be interested in other than something new that is Zelda, but we probably won't see anything else till after the new Hyrule Warriors game releases. I'm still hoping for a Wind Waker HD/Twilight Princess HD port, so that would be great to see.
For dream announcement...Either Rare Replay coming to Switch 2, or just a Banjo-Kazooie Collection announcement that has Banjo-Kazooie/Tooie HD, Nuts & Bolts, and the two GBA games, that would be nice, I just easily want to play Kazooie/Tooie HD without having to haul out my Xbox 360 from the closet lol
