The first priority for Eisler is getting Office 2008 out in the scheduled second-half of 2007 time frame. "Right now Craig is focused on getting ramped into his new role and the overall focus on the group is delivering Office 2008 for Mac in the second half of 2007," officials told MacNN. Meanwhile, the Microsoft MacBU remains the largest Mac OS X development house outside of Apple, with a current head-count of about 180 employees.
