Nintendo has announced it will launch a new version of its Wii console in 2012.

No technical details about the machine have been revealed, but gamers will get an early preview at the E3 Expo in Los Angeles in June. The original Wii proved a runaway hit for Nintendo when it launched five years ago. However, sales have been gradually declining in the face of tough competition from PlayStation, XBox 360 and mobile gaming platforms.

Wii was the first console of the current generation to offer motion controlled gameplay. In the past year, Microsoft has introduced its Kinect system for XBox, while Sony launched PlayStation Move. Nintendo's chief executive, Satoru Iwata suggested that his company was preparing a fresh innovation.

"It will offer a new way of playing games within the home," he said.
