What does this 'New Biometics' Notice mean? I485 Pending over tw

Thank you for sharing your experience or info!

Our 485 EB3 pending for over 2.6 years now. Today we (me and my wife) got notice for 'Biometrics' appointment. We had FingerPrints about two years ago.
Does this mean we need to do another round of FingerPrints again?? Or does this mean we will get the greenCard soon?

We are also one of the cases that were transferred to Texas center from Vermont center on 3/7/07.

Please tell us your thoughts!
Thank XiaBaiTu and all...
