Office 11 Betas

"As previously reported, concurrent with the rebranding, Microsoft officially launched Office 2003 Beta 2, which will be available to about a half million beta testers and businesses. Microsoft mailed the software late last week to the 12,000 people that tested Beta 1, which was released in October. Microsoft plans to ship Office System during the summer."
