Ok, remember the prototype version of the 3ds that was revealed to allow you to remove and swap the placement of the circle pad and the d pad? Well the Wii U should definitely have that, but beyond that, you should be able to remove the standard plus orientation of the abxy buttons and be able to place in an alternate version of the abxy buttons that are shaped sized and located where they appear on the gamecube controller. This would be great especially for when the new smash bros comes out, and you use the Wii U controller but want the feel of the controls you've grown accustomed to.
