I don't know if this is prior the email I got from Melissa. Anyway, yesterday she said mass production has started for the sets that have been reviewed. So we will soon find out.
Ya, it is not entirely clear, but my previous post was in reference to the quote that SpamRay posted. Basically, expect that some people will get their orders before others.
I think this is due to their new website and order management system. With the new system they can probably put the keys that are finished into the inventory on the site and it will probably tell them which orders are ready to be shipped. If this is the case they will probably try to streamline the whole process by shipping orders as they have all the components for them so they do not get a backlog of shipping at the end of the run. From a production and shipping logistics perspective it would probably be more efficient if they can start to ship during the production so they don't end up with a mass of shipping to be done at the end.
I have no idea how it actually works, I am just making some assumptions as the owner of a company that manufactures products and ships them. Don't take my assumptions as law...
