Sorry for my ignorance, but this is the first post I have seen on the net for a report of an actual delivery/shipping of the 645D gear (for the lens only up till now, the body is still under delivery, though):-

Btw, I wish the user can receive his 645D body very soon, and I also recommend you to visit his photo site, which has many great landscape and travel photos:-

P.S. The author of the website, Chris Wilson, is based in Okinawa, i.e., Japan, anyway.
Update (6-18): Chris has just received his 645D body. (via 1001 Noisy Cameras)
Update (6-20): Chris has posted four full-size samples at his flickr folder, via his blog.
Last "News": The (Postponed) 645D Release Day has Passed, Any News?
