iOS 8 banners grace Moscone Center as Apple's WWDC preparations continue

The banner features a simple, white "8" overlaid on a backdrop of turgid blue water. Business Insider's Jay Yarow was first to tweet a photo of the banner.

Industry insiders and Apple watchers widely believe the company will include a number of new health-focused features in iOS 8, including a new "Healthbook" app that would act as a central repository for health and fitness data collected from third-party products such as Nike's FuelBand. Shazam-powered song recognition in Siri and public transit support in Maps are also thought to be on the docket.

The presence of the banner seems to confirm that Apple will indeed unveil iOS 8 during next week's Worldwide Developers Conference. AppleInsider will be on hand with live coverage when Apple chief Tim Cook takes the stage on Monday at 10 a.m. Pacific, 1 p.m. Eastern and will continue our reporting from the conference throughout the week.
