Nintendo only recently unveiled the new 3DS XL portable game console with a much larger screen than the original 3DS offered. The original 3DS has an accessory to make holding it more comfortable and controlling your video games easier called the Circle Pad Pro. Nintendo has announced that sometime this year the 3DS XL will also get its own accessory.
The accessory is basically a clone of the product for the original 3DS. It will add an expansion on the side to make holding the 3DS XL easier and a second circle pad for additional gaming control. No pricing or release information is available.
