Looks like user presentations are a go at the 2009 ESRI Dev Summit.

At this point, it looks like we’re going to have about 10-15 scheduled slots. The capacity of the room will be between 50 and 70, so it should end up being a more interactive experience if you want it to be. This room will be part of the “Showcase” area, which is the central hub of the event. Then in the weeks leading up to the DevSummit, registered attendees will be able to vote so that particularly popular sessions can be moved into larger capacity rooms.

So get your presentation figured out and submit it. You have until February 9th to get it in.
