Here's what I got, and this includes games which haven't passed 10m yet, but might in the future
High chance of 10m+
Splatoon 2
Super Mario Party
(games which will/might be released)
2 more Pokemon games (one port, one new)
BotW2
Any new Mario platformer (2D or 3D)
Wii Sports-like game
So-So Chance of 10m+
Super Mario Maker 2
NSMBU Deluxe
Luigi's Mansion 3
Ring Fit Adventure
(games which will/might be released)
1-2 more Mario Party games
3D Mario collection
Zelda collection
Nintendogs
Tomodachi
new Monster Hunter
Minecraft
GTA V port
Just Dance
New IPs (first or third party)
Obviously, when I say so-so chance, some will make it and some won't and it's hard to predict which ones will. Also there is stuff on both lists that might get released but might not, but I'm putting it there because it's not out of the question. Also, even if a third party game reaches 10m+ there is no guarantee we will get a confirmation. Minecraft is a prime example. I have no idea how well it's done on the Switch worldwide so far.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
