I pre-ordered my Switch 2 this morning!

While I don't imagine it would be out of stock on launch day, pre-ordering just makes it more hassle-free (already paid for, the whole order is already packed together, etc.). I ended up buying the Switch 2 console alone, then the physical copy of Mario Kart World (because I'd prefer to have the cartridge), and then an SD card.
I don't have any plans to get the camera, and I won't get a Pro Controller, since I'd like to do what I did with the Switch and get coloured controllers when they're inevitably released. I'll probably get the Charging Grip at some point (I feel like I should have bought it with the above, but oh well)!
