With all the talk about Windows Phone 7 recently, many people are starting to wonder why Zune hasn't been mentioned at all. It seems logical that Zune software would be a part of a Windows phone, since Joe Belfiore, the Corporate Vice President of the Windows Phone Program Management said in 2010's keynote at Mobile World Congress “Every Windows Phone will be a Zune”. But now, nobody is talking about Zune. Is Microsoft getting ready to kill it off? Or are they just going to re-brand it?
