Nokia CEO Stephen Elop will join Microsoft and lead an "expanded devices team." Julie Larson-Green -- Microsoft's current overseer for Devices and Studio Engineering, which encompasses all hardware, including Xbox -- will continue to lead the division until the acquisition is completed, after which she will join Elop's new team. Elop will lead the new division, including Xbox, at that time.
