Online registration has sold out without Microsoft posting an agenda for the four-day event (five, if you include the pre-con day). Early-bird discounted Build registration ended as of August 1, as well.

While Microsoft is, no doubt, hiding the agenda to further the corporate mission of keeping Windows 8 features under wraps as long as possible, the “shhh” strategy has been a double-edged sword. I’ve heard from several developers that they were unable to convince their managers that they should attend because of a lack of information as to the sessions.
