Same here. Last year I ordered two iPhones. One said it was supposed to deliver two weeks after launch but I received both on launch day. Everyone needs to remain calm. It will arrive. And if by some chance I get my phone a week later I will live. It is only a phone after all. And even if I wait a week more to get it once I have it having to wait won't matter anymore anyway.
Most people will get their devices on launch day. Apple wants to get as many phones in the hands of people as fast as possible.
