Microsoft will ship an Office 2010 Technical Preview in July (they told me previously it would be a CTP). Attendees of TechEd will get the release automatically. But you can sign up to get on the waiting list if you'd like, too.
The Microsoft Office 2010 Technical Preview is a limited, invitation only program which will provide you with the opportunity to experience early, pre-release versions of Office 2010 which will include the following applications: Word 2010, Excel 2010, Outlook 2010, PowerPoint 2010, OneNote 2010, Communicator 2010, Access 2010, InfoPath 2010 and Publisher 2010.
By registering you are signing up to be considered for the Technical Preview Program, you will be waitlisted for consideration to be invited into the Technical Preview Program. We will notify invitees in early to mid July.
