There it is, in all its glory. Say goodbye to any aspirations of pocketing your 3DS if you get one of these. It is, of course, perfect for Monster Hunter Tri G, as it adds three additional shoulder buttons along with that second stick. As Capcom and Nintendo proved with the Classic Controller Pro, Monster Hunter players demand nothing less than a simulacrum of the PS2/PS3 controller. And this should probably turn out to be ... not terribly uncomfortable for playing that game. At home.
Oh, we just realized -- this adds a new 3D feature to the system. If you look at both circle pads and position your eyes just right, you should see one circle pad floating above the 3DS.
