Piracy -the main reason why Nintendo would have wanted to stick into cartriges. This doesn't mean that Nintendo wouldn't release Wii in China. Although, piracy makes game releasing a little less profitable. I don't think that everyone would get modchips to their Wiis and still someone has to buy the original copy. I do believe that Nintendo will release Wii in China, in 1 to 2 years. It will be a local version, like the Asian version of NES.

Nintendo games sell only on Nintendo system.
