I Just got this email :
We're writing to let you know that we will be introducing Google Wallet Merchant registration availability for Google Play Developers in additional countries. Beginning Feb 6 2014, developers from Indonesia, Malaysia, The Philippines, and Thailand will be able to sign up as merchants through the Google Play Developer Console.
This is a great news for Indonesian Mobile Developer community. We can start to sell all the apps in Google Play Store. Just create the Wallet and fill-out all the Merchant forms and settings.
