Earlier this week, Nintendo announced its February 7th US release date for the Circle Pad Pro accessory exclusively through Gamestop . If you've caught yourself wondering about its components, the guys over at ldblog were able to get their hands on the unit that you see above. Beyond basic capacitors for the peripheral's single AAA battery, there's a lot of empty room inside the case -- almost too much. The Circle Pad's spacious interior leaves us wondering, could Nintendo have used this room for an extra stylus holder, or perhaps, to accommodate the beefier AA battery? The world may never know.
