With the 2013 WWDC coming to the Moscone West Center in San Francisco next week, decorations for the annual event are being put up all around the venue. While we showed you one of the banners on Wednesday, the signs are really going up in earnest on Friday. These banners and signs remind everyone that minus a surprise device introduction, the biggest news to come out of the conference will be the introduction of the revamped iOS 7. Most likely the look of the banners is some sort of clue as to what we can expect from the revised UI designed by Jony Ive. The signs put up for WWDC 2013, show a flat, less glossy look that has long been rumored for iOS 7.
