With just 3 days to go before WWDC 2013 begins where Apple will unveil its latest iOS and OS X operating systems, purportedly along with a few new hardware announcements, banners of Apple's iOS 7 were hung up at the Mascone center in San Francisco where this year's WWDC event will be taking place. One of the main banners shows a colorful, thin and minimalist "7" (the new iOS 7 logo we presume) with a very subtle gradient background grid supposedly denoting a complete design overhaul of iOS - which is what we're all expecting it to be.

In addition, it looks like OS X will be receiving a more modern and minimalist facelift judging by the new OS X "X" logo plastered on one of the many welcoming, but mostly teasing banners at the Mascone center. There's no doubt Apple wants to convey a refreshing change. The two banners feature an identical sleek font that Apple has never used before indicative of a more uniformed design language being implementing across the two platforms. From what we can tell, this is a huge design change that leaves behind the glossy reflections and heavy bold design that has been present in Apple's repertoire over the years. Here's what last year's WWDC banners of iOS 6 looked like. So far we like what we see, sir Jony Ive.
