Another Microsoft employee has been appointed Nokia USA's President

Chris Weber
Total, complete, takeover
As for Microsoft getting Ovi Maps, Nokia actually makes the Maps for Microsoft already through Navteq (which is owned by Nokia)
Nokia's stock dropped 14% today and it's expected that in the coming days Microsoft may buy a stake in Nokia just to "seal the deal" -_-
And 1000 Nokia employees walked off the job (they'll likely be fired soon anyways but still)
