The upcoming Circle Pad attachment for the 3DS appears to be gearing up for launch, with speculation swirling with regards to what it'll be called. According to a trademark filed by Nintendo in Japan, the add-on could be called the ‘Circle Pad Pro’ in the West. This is already scheduled for release on 10th December in Japan, branded as the Nintendo 3DS Expansion Slide Pad.

If this trademark does become the official name, it at least shows continuity with the Classic Controller Pro brand from the Wii. This peripheral already has a decent number of games slated for compatibility, so it may find its way into quite a few 3DS owners' hands. Formal release details outside of Japan haven’t been forthcoming, but we’ll keep our eyes peeled.

What do you think of this name, and do you think you’ll be picking one up?
