This guy made a series of ipython notebooks based on the R exercises in the course. It's pretty interesting as it highlights some of the differences in implementation.
The course was excellent when I took it in January 2014. Or rather, the material is excellent (the book and the videos), the quizzes were usually useful (sometimes way too easy or way too hard), and the forums had good discussions (hampered only by the terrible forum software they use).
It's possible that they will redo the videos, but given the huge amount of time they must have taken to create, I would speculate that they will reuse the same videos.
