Most of the value in an MBA is from the face to face interaction and networking - the classes in business school are helpful sure but nothing you can't learn yourself in a book. If these schools weren't able to offer much in the way of networking and development of soft skills in the first place, then frankly going online makes sense because you don't lose anything, but i think that's a factor specific to these business schools, not the very top bschools that have no shortage of funding/extensive networks etc.
