Microsoft official announcement of just a slip-out. However, Microsoft Senior Vice President of Central Marketing Group Mich Mathews revealed during the Cannes Lions International Advertising Festival in Cannes, France that Windows Phone 7 will be released in October.
While introducing Microsoft General Manager of Rich Media Group Kostas Mallios to the stage, Mathews said:
“I’m gonna ask rock star Kostas… to come on. And Kostas has brought with him Windows Phone 7, which we launch this October.”
Now, that was the only detail that was revealed. It surely coincides with the “holiday 2010″ release date mentioned by Microsoft before.
