Not really, from what I understand most people who are familiar with the field say that with the way economy is more people are looking to attend medical school and that the number of applicants is increasing each year, naturally with a greater number of applicant comes higher admissions standards. As for D.O schools raising the requirements, I think they should. Accepting someone with a 20 MCAT is very questionable (although a dean of a particular MD school in Texas told us that they have), I think they should also raise the GPA requirements as it is more indicative of hard work, dedication, and intelligence, doing well on the MCAT on the other hand has a great deal to do with test taking skills and other factors, I know a lot of smart people who have gotten mid-20s on the MCAT, however, all of them had very good GPAs.
