I'll be talking at Unite 2013 - August 29th at 5pm. http://unity3d.com/unite/unite2013/schedule
For a sneak preview you can check out this article on using SketchUp and assets from Google Warehouse in Unity. I'll be demonstrating that live and answering questions.
I'll probably be up there for just that day - if you want to hang out sometime that day, get in touch!
