Nintendo has slapped a February 7, 2012 US release date on the controversial 3DS Circle Pad Pro.
It'll cost $19.99 and be available exclusively at GameStop both in-store and online.
According to the press release: "The Circle Pad Pro is a comfortable cradle that holds the Nintendo 3DS system while adding an analogue Circle Pad on the system's right side.
"The attachment also adds additional shoulder buttons to give it a feel more akin to traditional console controllers. It is designed as an optional accessory and is compatible with Resident Evil Revelations and Metal Gear Solid 3D Snake Eater."
Although the Circle Pad Pro requires just one AAA battery, reports from Japan have suggested that a single battery affords up to 480 hours of play time.
The accessory hit Japan at the weekend and will launch in the UK on January 27. European specific pricing has yet to be announced.
