For the last Kickstarter, I got an email notification with a tracking number, which I obsessed over for a full week before receiving my package. Maddeningly, I could see that my package had been received at the St. Louis shipping center and then sat there for days and days while they held it to make sure it didn't arrive to me earlier than they'd promised. :(
I think you've asked the question is exactly the right place.
I have two friends who have worked for UPS at the sort facilities, and they've been there at the same time as packages that were pending delivery for them but weren't allowed to take them home and had to wait until at least the next day.
lugaru, if you are moving on the 1st of September, you absolutely want to send Paul a message through the Kickstarter website with your new address. He'll update the spreadsheet with it, and then send it to me to update your packing list. And then we'll make sure the box goes to the correct place!
It's been noted in a kickstarter update as pointed out in the news that they will be going to PAX Prime this weekend, and that the mega shipment should be ready the first week of September. So, once they are back from PAX Prime, they should start shipping everything out.
