Apple’s smart glasses are among the worst-kept secrets in the tech world. Bloomberg’s Mark Gurman says the company’s first model, which will lack augmented reality features, will be announced at June’s WWDC next year. They likely won’t ship right away, however, with Gurman saying only that “glasses shipments would begin before the end of the year.” Key to their success will be the newly revamped Siri AI, which is adding fine-grained control over apps.
