We’ll hopefully be seeing some detailed early looks at both Vista and the currently-codenamed Office 12 at the event. The conference will be held at the Los Angeles Convention September and will go ahead from September 13-16, with pre-conference sessions being held on the 11th and the 12th.
Attendees will be able to ask questions to Vole bigwigs as well as "enjoying" features such as interactive labs and "many more activities," such as a gigantic IT themed ballpit (we made that one up). µ
I definitely cannot wait to see what the Office Team has been up to with Office 12 and Preview 2 of Windows Vista Beta 1 should also be of interest.
