After a great earnings call, Microsoft Chief Financial officer Peter Klein got a little loose-lipped and spilled that the next generation Microsoft mobile OS coming to Mobile World Congress. Klein says, when asked on Fox News, “We are heads down working on Windows Mobile 7 and we will have much more to say about that at Mobile World Congress in Barcelona in February.” Prior to Klein’s statement, Microsoft had been vague about its intentions for Mobile World Congress in Barcelona, Spain; the company only referred to its mobile strategy as the next generation mobile OS and never specifically mentioned Windows Mobile 7.

Hopefully, in announcing and/or demoing some key Windows Mobile 7 features at MWC, Microsoft can really begin to address those crazy Zune Phone rumors.
