Many of the sessions from Oracle OpenWorld 2007 are now online. You can query for the sessions at:
Unfortunately, I don't see the 'Futures' type of sessions posted there yet (despite the fact that I was told they would be there). Those sessions talked about some of the upcoming features of Essbase and the upcoming Essbase Studio (which I thought looked really cool!) I will try to contact the presenters to see if they will be made available there or to see if I can make them available somewhere on the web. I will keep an eye out for those sessions and other sessions I think are of general interest and will post some direct links if/when I find them.
