1. from what? SDN?!... c'mon.
2. they all have enrollment caps at the moment so I'm not really sure that they are increasing, do you have a link providing proof of that? yes western is coming, but I cant imagine it having class sizes as large as scholl, temple, nycpm, ocpm, I would assume it would be in between say azpod and dmu in terms of seats.
if you look at the AACPM website under statistics, it seems that some how, some way (i say this in part because of the lackluster approach the APMA has taken in regards to student recruitment until very very recently... and the schools have jusssst started to step up a little bit as well), there are more applicants every year.
speaking of SDN,maybe if we stop telling all the people who post one time asking if a 2.8 18MCAT is "good enough" that they are "in great shape, apply now!" and some how get college premed advisors to follow, the stats would go up.
...a lot of those people end up failing out anyway. if a school had a SOLID (I think that 3.4 24MCAT median is a good place to start) smaller class in which maybe all but a couple stayed all 4 years, they'd of course loose money for a couple of years, until the stats are up and the graduates are more uniform in intellect. word will spread "did you hear that podiatry is as competitive as DO?".
