Apparently Japan has more use for a tiny DVD player integrated with the Wii than the US or Europe, but Nintendo Japan’s just confirmed that they’re getting an “enhanced” Wii with DVD functionality.
There are currently plans to release a version of Wii in Japan featuring DVD playback. There are currently no plans to bring this model to Europe or the US.
Are they really so tight on space there in Japan that a regular DVD player is too big and they need one to be in their Wii? Then again, maybe with DVD playback modders will be able to burn Wii games onto DVDs.
