WeChat continues to grow and is now by far the largest mobile messaging app in APAC. It is, however, not only a messaging application but a full on social platform ready to go global. It is the main competitor for Facebook and Microsoft in social communications.
Facebook/WhatsApp is struggling to catch up. Skype will probably expand market shares with the new browser app. The other Asian darlings LINE, Kakao and Viber should consider merging to compete with the three big players if they want to be global, and not just regional, players.
This is probably the most important market right now, since it is not only about communications. It is also about e-commerce, social, search, translation technologies, the list is endless.
