Please note that the VSC has put the biometrics appointment notice ON the actual I-485 receipt notice, and you will NOT be issues a separate biometrics letter. However, this will change back to a separate biometrics letter very soon according to the USCIS I was just told, so check your I-485 receipt notice carefully when you get them. My lawyer missed that and I was informed by a person on this forum that his I-485 receipt notice has the biometrics appointment on it, so I check with my lawyer, and the admitted that he had missed that biometrics appointment notice information on the I-485 receipt notice.
