Mojipittan Wii
Developed by Namco and based on a hiragana tile-piling Japanese variant of Scrabble. Try to guess whether this’ll make it to western shores…

Joy Sound
Basically, Xing’s Joysound karaoke machine melted into WiiWare form. It’s developed by Hudson, and you’ll need their separately sold USB microphone to use the software. Interestingly enough, the download’s not a one-time deal, with updated track lists working their way from Hudson’s music mother brain to your console via the magic of eight-hour downloads.
