From what I've gathered here in Hong Kong (talking with distributors at retail and all that):
- The Wii will launch Q1 2007 (called Nintendo of Hong Kong and Nintendo's authorized distributor here and this was the best they could tell me)
- The Wii in Hong Kong will likely launch with English, not Japanese, as the system's language. Japanese isn't even an official language in Hong Kong, but English is, so if anything, the Hong Kong Wii will be English-based. Having said that, I would not be one bit surprised to see multilingual versions of the console for not just Hong Kong, but for Asia in general.
