UPDATE: No Man's Sky Explorers Edition - Ship from iam8bit

I just received a lengthy email from iam8bit. The gist of it said that the ship might not get to the consumers until mid-November.

Here's the most relevant quote from the email in regards to when to expect the product:

The "Explorer's Edition" is being finished as you read this email. We have been told by the plant managing the process that we can expect them, at the very latest, by mid-November. HOWEVER, they have also told us that it could be much sooner. The caveat being - these are hand-assembled, hand-painted and hand-packed, so it's hard to give an exact timeline.
