Yosi has announced that the presentations from the Microsoft Developers' Academy 2007 event are online.
Most of the presentation files I've seen are in English, but the videos are of the lecturers talking in Hebrew (except for Ron Jacobs's lecture), so if you're not a Hebrew speaker, you can skip downloading the videos.
