Well, that's a good question. The only info we've had from Gibbo is that a shipment is due to leave Hong Kong on August 12. Now, if this is going to be by ship, you can easily count 30 days in transit. If it's by plane, it will be at most 1 day. After that, there could be 7 more days of processing time in the customs.
So, based on these estimates, I would say that in the best case, they ship on the 12, arrive on the 13, only 1 working day in the customs, they are out on the 16, 1 day for inventory, they should start shipping to us on the 17 night/18 morning.
In the worst case, from August 12, arrive here by ship on September 12, 1 week in customs it's September 19, they get to OC on Sep 20, they start shipping them on Sep 21.
So, a safe bet would be that we won't start receiving them before the morning of the 19 in the best case.
Then, there is the question of the amounts that have been ordered. My understanding is that this shipment is the one that was supposed to leave Hong Kong on the 5, and will consist of only 50 cards. Then, there should be a further shipment, which was originally scheduled for the 12, that is apparently going to be "big", but what "big" means, and when it will actually leave HK, is up for discussion.
Of course, this is what I understand of what has been said so far. This means I may very well be completely wrong, and the only ones who can clarify these things are the OCUK staff.
