Today, Microsoft sent out an email to Click-To-Run Technical Preview participants that outlined the public beta which was announced by Microsoft last month; next week an email will be sent out to give further details.
This news follows the announcement of other closing Connect groups, such as the fully-fledged Office 2010 Technical Preview group earlier last week.
