Nintendo appears to have chosen a final name for its 3DS Circle Pad attachment.
The platform holder has registered trademarks in Japan for a 'Circle Pad Pro', which would seem like a fitting name for the optional second analogue stick.
First pictures and details of the peripheral came from Nintendo at last month's Tokyo Game Show, along with the Japanese pricing and release date.
The circle pad attachment will be launching on December 10 (the same date as Monster Hunt 3G) at a price of 1,500 yen, which is around £12 but don't necessarily expect a straight conversion.
It uses a single AAA battery and - the Nintendo Japan website is kind enough to point out - will not work on its own.
