There is one presentation from last year about "What's New in SAS Enterprise Guide and SAS Add-In for Microsoft Office". We'll have similar presentations at the 2009 session, covering even more of our future plans.
As far as allowing you to suggest features, you can always send your sessions via this form:
Each suggestion is evaluated for inclusion on the SASWare ballot, where you can then vote for your favorites. Even if it doesn't appear on the ballot, each unique suggestion does come to the development team. A good suggestion doesn't have to win an election before we'll consider implementing it.
