I won't be able to get a Switch till around April anyway so I just decided to pre-order the accessories that I wanted just to get them out of the way and dealt with.
This is what I got:
The Legend of Zelda: BOTW
Nintendo Switch Game Traveler Deluxe System Travel Case by RDS Industries
Nintendo Switch Official Screen Protection Kit by PDP
128 GB micro SD from Sandisk (didn't pre-order, just bought off Amazon)
Let me know what accessories you guys plan on getting and if you pre-ordered them before the Switch or not!
