Ships April 3rd. http://mugen.co/mugen-power-6250mah...xl-new-nintendo-3ds-ll-with-battery-door.html Pre ordered mine. Have one now for my launch 3DS, 3DS XL, and now my N3DS XL. I love them, if you can afford one I would highly recommend. Only drawback I see right away is maybe having to remove the battery if you need to access the sd card.
