I'm not sure Blender development is "agile" in the traditional sense of the term because from the outside there are signs that it is slow paced with high inertia (specialists in charge of large features, planning over many months, purpose-specific contractors and GSoC projects, features that are delayed until they are ready), but they are certainly successful at delivering copious, high quality and high value features. Let's hope that the good leadership continues.
