Apple’s upcoming Worldwide Developers Conference (WWDC) is expected to be one of its biggest yet. After years of rumors and leaks, Apple could finally take the wraps off of its mixed reality headset, entering the company into a new product category and giving the world a first look at its attempt to prove that virtual reality is worth investing in.
