Answered my own question above. Decided to buy one of the newer Wii U Nunchuks to see if the joystick box had changed. Sadly, it's still the old type 2 design. Really too bad there is not a known vendor selling those type 3 joystick boxes. I wonder what stickboxes are being used for the new Hori Gamecube and PDP Gamecube controllers that are just now rolling out?
