I doubt we will see this anytime soon in regard to AROTC. The Army Reserve and National Guard are still recruiting and in need, what could happen in the near future is AROTC will have a higher number of cadets sent to the Reserves/NG and fewer to Active Duty.
Internships will be harder for AROTC cadets given that they will now have summer training both the summer after their freshman year and the summer after their junior year. The summer after their sophomore year is traditionally when cadets would go to schools such as Airborne, Air Assault, or others. Not every cadets goes to this type of training and a cadet can opt not to go if they wish to do an internship that summer. Point is there will only be one summer cadets can do a full summer internship if they desire one.
I agree, with all the new changes it will be an interesting 4 years.
