Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Gold iPhone 5s Models Seeing Little to No Stock for Launch Day in Australia [Updated]
In a similar vein, it appears that the Apple Store iOS app has begun taking orders for the iPhone 5s in Australia, with Sonny Dickson sharing a screenshot showing that the gold 64GB iPhone 5s debuted with a shipping estimate of 7-10 business days.
It is unclear if the dearth of gold models will extend to other first-wave markets, but signs are increasingly pointing to the new color being very difficult to find at launch.
Update: The Australian Apple Store is now back online and showing 7-10 business days for colors and capacities of the iPhone 5s.
Update 2: Apple's Hong Kong and Singapore online stores are showing shipping estimates of October for all iPhone 5s models.
