Got mine last week at Walmart - called them up (had been calling daily around 1pm - about 4 local stores) and they said they just received 2 in. Drove straight to the store (about 2 minutes from where I work) and they were just putting them on the shelves.
I had already picked up Zelda, Elebits and Rayman.
So far I am loving Zelda, Sports and Elebits (having played much Rayman yet).
