24/7 Wall St.

While rumors have been flying that Apple Inc. (NASDAQ: AAPL) would be introducing its latest iPhones on September 9, the company did not make an announcement until Thursday morning. Even then, though, there is no reference to the iPhone or the iWatch, or any other specific product. Apple’s teaser: “Wish we could say more.”

The event is scheduled for 10:00 a.m. PT at the Flint Center in Cupertino, Calif., Apple’s hometown.

The company is widely expected to introduce two larger iPhones: a 4.7-inch model and a 5.5-inch model. A report Wednesday from Re/code’s John Paczkowski also said that Apple will use the occasion to unveil a new wearable device that everyone but Apple calls an iWatch.

What might we expect? Well, a sapphire glass cover for the smaller of the two devices is likely, and if there is an iWatch (or whatever it is called), it will almost certainly have a sapphire glass cover. The plant that Apple is building with GT Advanced Technologies Inc. (NASDAQ: GTAT) suggests that the sapphire glass will be available in quantity.

Another thing we should expect is a price point of around $650 for the 4.7-inch iPhone and something higher for the larger model. Apple, of course, has said less than nothing about the price of the new devices.

Another recent rumor is that Apple will boost the storage capacity of the larger iPhone to 128 GB, double the capacity of the largest storage amount currently available. Combined with a 5.5-inch screen and some other new goodies, it is conceivable that such a device could cost more than $800.

Now that Apple’s committed to an announcement date, the rumor mill will begin churning out even more “product.” That should keep us entertained until September 9.
