Specialties

Hi, Just been accepted to a DO school, and I was wondering what specialties are open to average DO students after ACGME and AOA residency merger? I didn't say I was interested in primary care or rural medicine on my interview trail and I don't really want to be locked into primary care if I don't do well at all. Are surgery, ENT, ortho, anesthesiology, ER, or literally anything that's not primary care still visible if you are like ~50% of the class?
