Secret Scoop! The extra 3DS Circle Pad peripheral/cradle revealed (click for a larger image of this larger 3DS). Along with the extra analog input, this adds R1, R2, and L2 buttons. I am predicting that added bulk, particularly in its thickness, serves as a battery pack, too.
Forum threads and blog comments are brimming with questions — and anger — about the device: Is this just for Monster Hunter Tri G, or will plenty of future games require this? Is that rumored hardware revision, which adds the new Circle pad to the base design and thumbs its nose at early adopters, also in the works?
This actually reminds me of the Classic Controller Pro’s release alongside Monster Hunter Tri for Wii, which was designed to provide a better grip, improved analog pad placement, and bigger shoulder butons. I suspect Capcom asked for this peripheral to improve the Monster Hunter experience. We’ll find out soon how much of the 3DS’s future Nintendo is investing in this attachment.
