Originally announced at the iPhone 5 event in 2012, the game Clumsy Ninja launched for iOS today. Interestingly, Apple is promoting the game in some international App Stores (both on iOS and OS X) with a video trailer. The trailer is a demonstration of how the app functions. As MacStories notes, it would be great for developers if these video trailer is a sign that Apple will allow all developers to include trailers in App Store marketing materials for their apps.
