Will Apple Retail Stores refill stock one day after launch day?

If in any way an Apple Retail store runs out of stock after launch day of the new iPhone 6, is there any chance that by the next day there will be new stock already again? Or does sold out mean = sold out for a few weeks.

Not likely it will take a bit once they are sold out.

No, its takes longer to fill. When I bought iphone 5S I had to wait about 2 months, but I also was going to verizon store, apple store most likely has more supply
