Does this mean I will get the green card?

I got an email as follows:

Application Type: I485 , APPLICATION TO REGISTER PERMANENT RESIDENCE OR
TO ADJUST STATUS

Current Status: Card production ordered.

On March 31, 2008, 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. You can also receive automatic e-mail updates as we

Does this mean I will get the green card in a month?
