I can see why people are interested, but I worry that the more information that gets released, the more likely someone is going to fit the pieces together and establish an identity.

While I choose not to publicly speculate about Satoshi's identity anymore, reading these emails is certainly causing my to reconsider my privately-held theories.  And there's a strong likelihood that hundreds of other people have invested far more time and consideration into pondering this mystery than I have.  There's no way of knowing how close someone might be or what new clue might finally solve it for someone.
