@SteveStreza has been haunting the Moscone West convention center in San Francisco the past few days and zapped some photos to the good folks at MacStories.net. As just about everybody on the planet expected, iOS 6 will be announced at WWDC 2012 as these photos of the big new banners on the first floor indicate.

Streza and MacStories were kind enough to give us permission to run these photos, which are sure to stir up more excitement. Streza also noted that banners on the second floor of Moscone West tout Messages, Notification Center, and Game Center for Mac.

Be sure to join us on Monday morning (June 11) at 11:30 AM ET for a pre-keynote episode of TUAW TV Live, followed by our metaliveblog of the event at 1 PM ET.
