I called Japan inquiring about Hong Kong. They also said mid 2004. They said that it is a new model and they will evaluate performance, make enhancements, etc. based upon the feedback from the Japanese market.
Am also on the fence now as to whether to get a DV-50, wait for the UX-1, or both. The list for both units is 1.2M yen or so.
Has anyone heard it yet?
