The Cupertino, Calif.-based firm has often used WWDC as the launch pad for new hardware, unveiling the iPhone 4 in 2010, the iPhone 3GS in 2009 and the iPhone 3G in 2008. Last year, however, despite rumors swirling about a new iPhone, Steve Jobs used WWDC to showcase the company's iCloud. Apple fanboys had to wait another four months for the launch of the iPhone 4S. Investors, though, clearly got over the shock of a hardware-free WWDC. Apple's shares rose almost 9% between the June developer event and the iPhone 4S debut in October, compared to a broader slump in the tech sector that saw the Nasdaq tumble 12%. ISI Group analyst Brian Marshall will also be looking out for updates on key product metrics when Apple CEO Tim Cook takes the stage to present his keynote on Monday. "We expect metrics provided this year will be supportive of our estimates of 140 million iPhones, 64 million iPads and 19 million Macs in calendar year 2012," he explained, in a note. Apple sold 35.1 million iPhones, 11.8 million iPads, and 4 million Macs during its recent fiscal second quarter. What do you think Apple will announce at WWDC?
