In Japan, the new second-thumbstick add-on for the Nintendo 3DS is simply called the "Circle Pad Expansion". Not very exciting, but it at least gets the point across.
In the West, though, it looks like it'll have a different name. A trademark filing from Nintendo in Japan has revealed that the peripheral's name in places like the US and Europe will be likely be the "Nintendo 3DS Circle Pad Pro".
The Pro? What happened to the "Nintendo 3DS Circle Pad Standard Edition"?
