Certified Developer exam blueprint?

So I've got myself registered to take the Developer exam this year at K15, however, I have no clue as to the depth and range that the exam will cover. SN provides a blueprint of what to focus on for the Admin exam but, what's the scope of the Development Exam. I've taken the scripting class, been using the tool for two years now, and watched all of Chuck's videos but, there's so much that could be considered Developer material.

Any thoughts or ideas appreciated.
