Here is an image, of another peripheral gun for the Wii called "Wii Blaster". Now, dont confuse it with the Wii Blaster from JoyTech. It seems that GameStop has a new "Wii Blaster". Scheduled for release on June 26 by a company called Core Gamer, the Blaster houses the Wiimote in a casing shaped like a shotgun.

Looking at the other products that Core Gamer makes it will just be a housing similar to that of their Sports accessory pack and controller grip.
