Ok I had a longggg talk with WU Admin.
I asked her about the pharmcas information regarding to last year's class, and she said it was true as of April 2008. After the last interview they only accepted 92 applicants. Eventually 28 people did get pulled off the alternate list to fill in those spots (the top 28 altnernates and she hinted that it looks like this year's list too).
However at the end of the admissions period (August 10th) there were a total of 45 people who got pulled off the alternate list and actually accepted Western's offer of admission. many of the alternates declined the offer and went somewhere else.
Western's non-ranking policy is "truly torturous" even she doesn't like it because she understands what we go through. She said although it's non-ranking but she knows the admin do have top alternates. For the re-evaulation, they will be mostly focusing on essays and short answers to see how we are different from each other, assuming that we did similarly during the interview.
One information she gave me is that starting this week some alternates will be getting a phone-call from Western to fill up some of the seats available because they do not have a full class right now!

(let's pray that it's us)
Also it's a good idea to start reapplying starting in June.
