Apple's WWDC iOS 8 Banner Courtesy 9to5Mac

Surprising exactly no one, Apple has unintentionally confirmed iOS 8, the next version of its mobile operating system.

Gearing up for WWDC, its annual conference that kicks off Monday, Apple (NASDAQ:AAPL) has started decorating the Moscone Center in San Francisco for the event.

Apparently referencing Apple’s coming iOS version, a large banner with the number 8 over a watery background has been hung in the conference center. While we know what the number means, the significance of the ocean background is vague. Perhaps it will be a theme of the event.

First published by Business Insider’s Jay Yarrow on Twitter, the banner is the first official sign from Apple that iOS 8 will be discussed at the conference. Other topics to be discussed are OSX 10.10, new hardware like the MacBook Air with Retina and updated versions of the MacBook Pro line. Less likely to be announced are the iWatch, iPhone 6, or any update to the iPad lines.

While iOS 8 seems to be a straightforward update from iOS 7, with some rumored new feature like a health and fitness app called Healthbook and an update to Apple Maps, the update to the Mac operating system OSX is less clear. Whether it will be called OSX 10.10 or OS11, it is speculated to have a completely redesigned look and feel now that Jony Ive is at the helm.

Ive, Apple’s head of design, was the key player last year when iOS 7 got its new look, so OSX should see some similar stylistic quirks. But whether Ive changes small design looks or completely overhauls the OS is still to be seen.

WWDC starts on Monday 2 at 10 a.m. PDT/ 1 p.m. EDT. Apple will be livestreaming the keynote address.
