The cat is slowly emerging from the bag, it would seem. We knew that Picross DS was in Gamestop's computers as a July release, and now the ESRB has pretty much confirmed it by rating the game.
Just think, this summer we could be filling in squares and making pictures just like they do in Europe. Well, you could be. Availability isn't the issue for us; being able to buy the game isn't going to magically make us less awful at Picross.
