Nintendo 3DS Expansion Slide Pad, but you may very well be. Here's hoping you also live in Japan, as the device is currently available for pre-order on Amazon in its country of origin. As previously revealed, the Slide Pad launches in Japan on December 10 for just ¥1,500 ($19.50) and works with several 3DS titles. Oh, and if you really wanna grab one and you live somewhere outside of Japan, Play-Asia's got you covered.
Of course, if you're the kind of person who's counting the days until Monster Hunter Tri-G launches, you've already pre-ordered the bizarre attachment, haven't you? You can tell us, it's okay.
