I am still expecting Apple to announce an application SDK and App Store for the Apple TV. Or, maybe AirPlay will be way more useful with streaming almost anything from an iOS device to an Apple TV, so it can be displayed on a TV. Just think if you could stream playing Angry Birds on your iPhone to your Apple TV, then the iPhone becomes a remote and gaming console for your TV.
