We still have ~10 sessions we're working to confirm, but there are over 30 posted on the website here: http://jamfsoftware.com/events/user-conferences/jamf-nation-user-conference-2012/sessions.
Also, the event schedule with session dates/times should be out in the next week or two. Hopefully that helps make the case; it'd be great to see you there!
We just updated the website to add more sessions and the detailed schedule! Everything is available here:
See you in a few weeks!
