Here is what we think we know about what Apple will announce at WWDC on Monday about Apple TV. It will be releasing an SDK to allow developers to create apps for a new Apple TV App Store which will be part of iOS 6. The existing Apple TV device and an improved version of AirPlay will enable iOS devices to control the TV screen through mirroring and dual screen apps. iOS 6 will be deeply integrated with iCloud, which will bring email, contacts, calendars, documents, music, movies and photos all to the TV screen in a way that is fluid and synchronized with all of your other screens.
