I pre-ordered 2 3DS units from amazon (you can pre-order 2 if you get 1 of each color).
I still may cancel both pre-orders. I am currently trying to see some indication that pre-orders will sell out and the 3DS will be in short supply.
Personally, I don't need a 3DS yet. There are enough good DS games coming in 2011 to keep me busy.
I will be more interested in a 3DS once a new Mario game is released.
Most anticipated games of 2011:
Uncharted 3,Legend of Zelda: Skyward Sword, Rocksmith
Modern Warfare 3, Super Mario 3D
