Just found this pic in the gallery, now there are two add-ons to the wiimote, the gun and a cube controller-like attachment!
That brings the different controller options up to what 6? wiimote, gun attachment, classic controller, cube attachment, regular cube controllers (don't know if these will work on wii games, but if they made a wiimote attachment with the layout then prolly), i guess we can assume the dk bongos will still work....
whats next? a steering wheel for the racing games? a hilt for swordfighting?
though i hate to put a little rain cloud over the wii right now, it looks like though the system is going to be pretty cheap nintendo wants to really make that back by selling as many different controllers as they can.
