I feel it should happen soon, but know that it will not.
If it were up to me, an accreditation body would make all US medical schools grant the MD degree, and give a short number of years for the medical schools to rise to the minimum requirements for accreditation. If a school can't meet those standards, they'll be on probation until they can fulfill the requirements and or be shut down (not sure how you can shut someone down if they're private).
Of course, I'm just dreaming here. I feel that DO's should become MD's and the new MD's that are interested in OMM can enroll themselves in OMM education as they see fit. I don't feel it should be mandatory since such an insignificant number of physicians utilize OMM.
People get bent out of shape if they're a DO and are called or listed as MD. To me, MD = medical doctor which technically a DO is a medical doctor, so who cares. But I digress.
