Apple is set to release its FY16 Q1 report tomorrow, and today Fortune has released their results of an analyst survey conducted ahead of Apple’s upcoming announcements. Fortune indicates that Apple may actually report the “most profitable quarter in the history of capitalism”, but investors are more concerned with the iPhone’s trajectory numbers as to indicate what may happen in the coming quarter.

Although Apple has already announced their biggest ever holiday season for App Store sales, Wall Street is still eagerly waiting to hear what revenue Apple expects to collect in this coming quarter. Although Apple doesn’t normally share iPhone sales targets, Fortune’s survey showed that averaging various analysts estimates, they have been able to closely identify the iPhone unit sales.

It appears that from Fortune’s survey (shown below), professional analysts predict Apple will announce a revenue of $55.75 billion, while the amateur class predicts $60.35 billion. Both these estimates appear to be right around last year’s results, $58.01 billion, yet both groups estimate iPhone unit sales will be lower as well.

As March is expected to be a busy month for Apple, with new Apple Watch bands and a new 4-inch iPhone resembling current recent designs, tomorrow’s report could give potential ideas on where Apple believes their strongest sales will be.

Fortune’s also included a video in the article that further explains some of investor’s concerns with the iPhone’s unit sales. Apple has seemingly reached maximum saturation with their iPhone sales as customers aren’t looking to upgrade year after year to the latest devices. This fact, amongst many others, is what could help explain the 20% drop in stock as of the last six months.
