There are Wii price-cut rumors that should become reality this weekend at least in the United States. The UK is rumored by MCV to get a new Wii bundle.

The new Wii bundle would include the Wii Console, Wiimote, Nunchuck controller, a MotionPlus module and both Wii Sports and Wii Sports Resort.
The source of MCV for this rumor does not know about a price-cut. So Nintendo may just add more stuff and keep the price the same.
Currently the Wii console including Wii Sports sells for £179.99 on Amazon UK.
