Wow! A lot of hyperventilating on this thread! Reminds me of the pre-allo forum of a few years ago.
Relax kids, the osteopathic profession isn't going anywhere. Remember they survived the MD's best attempts to throttle it; now they're co-equals (except maybe in the minds of some naive pre-meds on other message boards.)
You can't open a DO program unless you can ensure adequate rotation slots, but for residencies, theoretically students can be thrown to the winds. That sounds scary, BUT, there are still more residency slots than there are DO AND MD grads. Imagine the lawsuits that will ensue when grads can't find jobs (like law school grads are faced with now. Some people are now making noise about either closing some law schools, or reducing class sizes. BUT, that doesn't apply to the medical profession, as there is still a need (and growing) for doctors, but there's a vast oversupply of lawyers.
The numbers of medical grads will be increasing as new DO and MD programs come on line, but I see the FMGs being the ones squeezed out.
Both AOA and ACGME have their best interests in merging residency programs, not keeping them separate. That merger will happen. Just give it time.
And both DO and MD schools have an interest in keeping out grads whom both rejected.
So quit fussing.
