Apple will hold its next quarterly earnings call with investors on Tuesday, July 23, where it will discuss its fiscal third-quarter results. According to its own estimates, it expects to report between $33.5 billion and $35.5 billion, a drop from the previous quarter but a realistic figure in light of no refreshed iPad or iPhone, the two primary drivers of Apple's income. While the latest MacBook Air revision has garnered significant praise for its various improvements, it emerged at the very tail end of the quarter and thus didn't influence sales.
