Today, just before E3 kicks off Nintendo have released a bunch of images that show the different ways in which you can use the Wii Remote.
"Depending on the game, the Wii Remote could be a weapon, a baseball bat or an airplane. The applications are limited only by imagination. The Nunchuk controller attachment also includes a motion sensor, a development that suggests additional creative possibilities for this dual control system: Games could involve the use of a sword in one hand and a shield in the other. Or a clamp and a scalpel. Or a pair of boxing gloves."
Check out these images, they should give you a nice idea as to how the controller could be used.
