All; Here is a new MBA program Cornell University, within 12 months. What is interesting is the fact they you will be credit with 15 credit hours upon acceptance into the program. It is very expensive cost Tuition for 2007-2008 is $67,700, which includes the summer term. Here is the link http://www.johnson.cornell.edu/academic/accelerated/
I wonder if you still have to take the GMAT/GRE if you have a PHD. Most other MBA programs waive the GRE, if you have a doctorate.
