It's all supply and demand short supply equals high demand. We can look at this two ways. 1. Apple is creating a demand for the iPhone 7 by limiting the amount available in the coming weeks. Who knows, they could have a warehouse full in China and slowly release them over the next few weeks, or 2. Apple didn't meet their sales numbers they were hoping for with the 6s so they were testing the waters with this release and not as many went into production. Even with the 10% production increase reported last week it still wasn't enough to meet demand. Ether way it's just business, and every one who wants a iPhone will eventually get one. Maybe not on release day, but I'm sure sooner rather than later.
