I didn’t see this at Tokyo Game Show, but Tomy is planning on releasing a Choro Q game on the Wii this winter. Choro Q isn’t a serious racing game like Gran Turismo. It’s more like the Xbox 360 racing game Mad Tracks where you drive up loops in tiny cars. And one of them is shaped like a rubber duck!
No word on a US release yet since it's just been announced, but considering how many Wii games have been getting localized I wouldn't be surprised to see some company work on localizing Choro Q Wii in the future.
