Do you have a link to that? I've been trying to find an official one. Edit: NVM, found this: Clip: "Walker said that Google is committed to maintaining free calls to the U.S. and Canada through the end of the year, and that the current plan is to maintain this rate. He said that Google believes it can make enough money on international calls to sustain the service." If I were to guess I'd say US and Canada remains free after the end of the year.
