At ReMix conference, Paris, a Microsoft slide revealed that IDC had forecast "30 million Windows Phone 7 devices would be sold by end of 2011". As it turns out, IDC had said no such thing about the future operating system, on which many observers believe Microsoft's mobile-phone future depends. Instead, IDC forecast 2011 sales of 32 million devices running all Windows Mobile OSs. This includes expected sales of devices with Windows Mobile 6.5, which's already on market. IDC hasn't given any sales estimate for WinP7, which Microsoft has said will be available in 4th-quarter.
Microsoft said in a prepared statement that "the slide was inaccurate, and intended to represent an analyst's assessment of the market opportunity". The redmond company added that it hasn't provided any sales forecasts of its own for the OS. IDC won't be able to forecast sales of WinP7 devices until the OS is on sale and it has been able to talk with mobile operators and hardware vendors, mobile analyst Will Stofega said.
