Nevermind that big shake-up this week at its mobile unit, which has now been put under the direct auspices of CEO Steve Ballmer. Microsoft (NSDQ: MSFT) still has very high expectations for this fall’s launch of Windows Phone 7. A slide the company presented at its ReMix developers’ conference — captured by MobileTechWorld — shows it expects 30 million phones to be running Windows Phone 7 by the end of 2011; the slide — which is derived from IDC data — notes that there’s a big opportunity since so many people globally still don’t have smartphones.
Still, as many commenters on the web are shouting this morning the figure seems unrealistic. Apple (NSDQ: AAPL), after all, only sold 21 million iPhones during its 2009 fiscal year. AllThingsD checked in with IDC which clarified that the projection includes both sales of Windows Phone 7 as well as sales of previous versions of Windows Mobile. Still, as Mary Jo Foley points out, it’s hard to believe that sales of older versions of the mobile operating system will amount to very much — which means that the bulk of that figure is in fact coming from Windows Phone 7.
