Coursera's delays were because it is much more closely affiliated with Stanford than Udacity is. In the fall they didn't really have the Coursera name settled upon yet and the certificate printouts they sent to people who completed the courses had Stanford's name on them.
Discussions involving university reputations are always going to be long and dragged out. Udacity avoided them by having a clear separation between the website and the institutions of its instructors from the outset. Coursera acquired that separation over time.
Harvard and MIT's reputations are most of what separate them from FullSail and the University of Phoenix. It is important that they protect them. It is encouraging that more universities are following Stanford into this space.
Courses with broadcast lectures and server-based practice/homework/exams will need the (hu)manpower that universities currently command in order to grow quickly.
