Wustl 3L OCI will likely be abysmal this fall (Fall 2009) by Tier 1 standards. That having been said, that has to do entirely with the economy. You can argue the pros and cons of whether a firm will want to hire you over a 3L who is reinterviewing based upon start dates, economic projections or whatever stigma (good or bad) you want to go by.
However, rest assured that it will be infinitely better than your T4 OCI. I am surprised, but Vandy's OCI has a lot more employers than we do. But, as I recall, Vandy counts every office that a firm is interviewing for as a separate.
Long story short: transfer if you can afford the full tuition. It's expensive; be mature about your decision. Hope for the best, but plan on having a job that makes about 50k out of law school.
