It’s possible that Siri could appear on Apple TV in the future, judging by code found in the iOS 7.1 SDK. According to 9to5Mac, an SDK file showing which platforms are compatible with Siri uses the number 3 as an identifier — the number 3 internally represents the Apple TV family in such cases.
The code is present in iOS 7.1 and 7.1.1, but not in iOS 7.0.6. It’s possible Apple could introduce Siri in the rumored upcoming version of Apple TV.
