Some of the most popular features requested by users are already available in the online interfaces: group chats, invisible mode, AIM integration, so we should expect to find them in a new release of Google Talk. Other features are already standard in other IM clients: video conferencing, conference calls, phone calls.
Last year, a presentation for Google Apps inadvertently included a screenshot of Google Talk enhanced with the ability to make phone calls. In the comments, someone informed us that "internally at Google, this feature is already active since long".
What would you like to see in this all-new version of Google Talk?
