The official page for Star Wars: The Old Republic has been updated with a new blog post by Georg Zoeller, Principal Lead Systems Designer. In his post, Zoeller talks about the Advanced Class System and the complexities in designing it well. Zoeller then goes on to give some concrete examples of the design process for the Smuggler class as it moves into either the Gunslinger or Scoundrel Advanced Class.
