If I go to the website and try to place an order today, it now says pre-order for "release date Wednesday, 9/29" - so I think that that is when stores will receive new stock. I bet the order I placed on Tuesday this week will be fulfilled then and that there is no stock for launch day tomorrow or before next Wednesday. Interestingly you can get it shipped express and have it to your house by Monday of next week (but this complicates the trade-in so I won't be doing that) but if you select free shipping it will deliver for a next Wednesday arrival (which is the same day as the store stock refresh). I cancelled an Apple Store order because the Best Buy deal was better, so waiting most of a week for the savings is a bit frustrating but still worth it in the end.
