As far as games I plan on getting on release, there are currently 3.
Vampire Survivors is a game I've been dying to see a Switch port of ever since I first played it, so I'm all in on that next month. Maybe this version will finally be the moment when we find an actual vampire? Not ghosts, though. There's never been ghosts in this game. Ghosts don't exist.
The thread title refers to "Planned Purchases", but well, the other two are games I've already paid for, courtesy of that 2 game voucher scheme NSO offers. I used both of them on Super Mario Bros. Wonder and Super Mario RPG. 2D Mario hasn't steered me wrong yet. They're good at worst, and I doubt that kind of Mario is going to suddenly be open-world and boring, so safe bet there. And Mario RPG is, well, Mario RPG. Love that game. Very intrigued to see how they handle certain aspects of it. And maybe Mallow and Geno will be useful and not just benched as soon as you get Bowser and Peach?
The rest are various games that have been added to my "I'll wait for a decent sale, because I have a backlog, and don't need to play these immediately" wishlist. Wonder Boy Anniversary Collection is 30% off, so I snapped that up, which means I now have every Wonder Boy game on my Switch.
