A week after "mid September" came and went, I emailed to ask for another estimate from them of when they might ship. After several days, the reply I got late yesterday was:

"Sorry for the delayed response!! This week, we have been busy with shipping out the 1/350 scale orders. The 1/700 orders will be prepared and shipped out next week."

That is a direct quote.

So, for whatever this is worth. For my part, I then expect from this reply that I should get a notice that it shipped just about one week from today. Fingers crossed. (And if this doesn't prove true, I am not shy about making more inquiries!)
