Microsoft may share some of its plans for the future of the Zune HD at the same time as its mid-October launch for Windows Phone 7, an insider claimed today. The contact didn't necessarily expect new players to arrive but hinted that Microsoft CEO Steve Ballmer might discuss the future of dedicated Zune devices at the same time. The most likely opportunity should be the October 11 open house event, where many of the company's latest offerings will be on show.
