Some of the announced course are due to start as late as February 2013. Since the academic calenders in most universities are prepared well in advance, they need to sign up the profs much before the actual course date. Announcing the courses early will help them gauge the level of interest. This will help in deciding which courses they can offer after these ones.
It seems kind of like they bit off more than they could chew. Even the courses that are now running were delayed 2-3 months. But that's natural for any new venture. I think with more iterations, they'll get better at it.
My guess is that the biggest hurdle isn't the technical challenge but professor retention. I would imagine that some professors sign up but then a big grant or other obligation comes up and they just no longer have the time.
