I485's approved?

My wife, son and I got emails from USCIS see bellow. Means approved? When get Green Cards usually? EB3 China, PD 5/27/2005. Thanks!

Application Type: I485 , APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS
Your Case Status: Card/ Document Production
On May 22, 2012, we ordered production of your new card. Please allow 30 days for your card to be mailed to you. If we need something from you we will contact you. If you move before you receive the card, call customer service at 1-800-375-5283. 
This step applies to applications that result in an applicant receiving a card (such as a "green card") or other document (such as a naturalization certificate, employment authorization document, travel document, or advance parole).  Applications will be in this step from the time the order to produce the card/document is given until the card/document is produced and mailed to the applicant. You can expect to receive your card/document within 30 days of the approval of your application.
