You'll probably have better luck with speculation about that in the general forums. My own thoughts are that, in general, those who successfully gun for competitive fields are going to do so regardless of the match situation (if anything, they may fare better because they can apply to both traditionally MD or DO programs without withdrawing from one or the other out of fear of not matching anywhere/giving up on a shot at matching to their dream place) and those who are aiming for something much less competitive aren't really going to be all that affected because region seems to play a pretty large role/those fields are already pretty unbiased towards DOs in most regions. Ultimately, it still has to happen and, then, only time will tell.
Since it's not all that easy to come up with honest answers regarding match rates (if a school releases information it's generally going to be favorable information for the school, are they including/excluding scramble "matches," etc), who really knows...
