Here's the early artwork for the Collector's editions steel Enchiridion packaging. Yet, there's more with a stylus in the shape of Finn's Gold Sword, an art book, an activity book and and fold out poster of Ooo. Not sure yet if the activity book and art book are together.
You can get two editions one for 3DS or plain ol' DS here
