Let the hype begin

$Apple (AAPL.US)$ just gave everyone the big heads-up they were waiting for. The tech giant's Worldwide Developers Conference is set for June 5 to June 9, with CEO Tim Cook kicking everything off. Usually, Apple will use the event to unveil new iPhones, iPads and software. This year could be different, though, as the company is widely expected to unveil an augmented reality headset. And, as CNBC's Kif Leswing points out, Apple may take the opportunity to show off new, high-powered Macs to the developer-heavy audience at the conference.
