My understanding is that no news is good news.
I was told that if you receive any written correspondence it will be to tell you that you will not be offered an interview.
If it's been a while, you might consider a call to Tracy Takara to put your mind at ease.
Also, I was told that the last batch of applications from 2003 will be sent before the interview committee this week to determine who will be invited to Phoenix.
Best of luck.
