And it is apparently called "Wii Remote Plus".
The box art for upcoming Wii title FlingSmash seems to be bundled with a new Wii Remote. The box notes, "Bonus Wii Remote Plus Inside!" The game is compatible with Wii MotionPlus, the motion add-on peripheral for the Wii Remote. The Wii MotionPlus was released in 2009 and offers more precise motion control.
If this box art is correct, then Nintendo is releasing a Wii Remote that features an on-board integrated Wii MotionPlus. The game and the remote are bundled together and priced at US$49.99.
FlingSmash will be published by Nintendo and was originally supposed to be out this summer, but has been pushed to November. A new remote could explain the delay.
Earlier this year, Nintendo submitted a slightly modified version of its Wii Remote to the FCC. The company said in 2008 that it was considering integrating Wii MotionPlus technology into the standard Wii Remote.
