The new Apple TV ships with the same remote everywhere but Siri on the set-top box is only supported in these eight languages and countries: English (Australia, Canada, the United Kingdom and the United States, German (Germany), French (France), Spanish (Spain) and Japanese (Japan).
Why is that? After all, Siri on the iPhone, iPod touch and iPad support the most basic features in a total of 29 countries, as per Apple's iOS Feature Availability webpage.
Based on an interview that the German-language blog MacPrime conducted with several Apple TV project managers, it's all about the differences in the pronunciation of actor names, films and directors in various countries. But rest assured, Apple is already hard at work on training the Apple TV's Siri for additional countries.
