June 07, 2012, 4:52 PM — Apple will kick off its annual Worldwide Developers Conference on Monday and speculation is rampant about what the company has in store for attendees and Apple fanatics around the globe. WWDC 2012 will include purported refreshes to almost the entire Mac lineup including the Mac Pro, Facebook integration for iOS, Siri integration for the iPad, iCloud improvements, as well as sneak peeks at iOS 6 and the previously announced OS X 10.8 Mountain Lion.
WWDC 2012 promises to be a big show if all the rumors turn out to be true. So here's a look at the latest buzz around Apple's annual summertime conference, which starts with a keynote address on June 11 at 10 a.m. on the West Coast.
Big Mac
After languishing without a refresh since summer 2010, Apple's desktop tower, the Mac Pro, is receiving an overhaul to be introduced during WWDC, according to 9to5 Mac. There will reportedly be three new Mac Pro models, one of which can be used as an OS X server. It's not clear what new features the Mac Pro will have, but good bets include new Intel Xeon E5 chips, Thunderbolt I/O technology and USB 3.0 ports. Adding to the Mac Pro speculation, Mac Rumors recently reported that Mac Pro availability at Apple retail stores is dropping, suggesting that new models are on the way.
There is also some speculation that Apple will refresh its iMac all-in-one desktops.
iOS 6
Most Apple watchers believe the company will at least give a sneak peek into iOS 6, the next version of Apple's mobile platform, even though it's not expected to debut until the fall. A popular rumor that started on TechCrunch says Apple will integrate Facebook into iOS, similar to what Apple did with Twitter in 2011.
