Circle Pad Pro gloms onto 3DS on Feb. 7, exclusively at GameStop for $20

You'll be able to get your hands – and specifically your right hand – on the Circle Pad Pro in the US on February 7th, when the peripheral goes on sale exclusively at GameStop for $19.99. That's a full two weeks before the PlayStation Vita reminds portable gamers why a second analog stick is so important.

In addition to the obvious second stick, the Circle Pad Pro adds "additional shoulder buttons to give it a feel more akin to traditional console controllers." You'll get to put those shoulder buttons and that second stick to work playing both Resident Evil Revelations – which is much better with the peripheral – and Metal Gear Solid 3D: Snake Eater, which is targeted for a loose Q1 2012 release. While both Revelations and the Circle Pad Pro share a February 7th release, they don't appear to share Europe's "special limited edition" bundle offering. That's alright, you're probably waiting for the inevitable redesign with the second stick built-in, right?
