My passport was stamped late Oct. 2002. I received my plastic card Apr 28, 2003, about six months later. Also from CSC, stamped in San Jose.
The online message was changed to 'card ordered' last week, April, the 16th. So, it took about 2 weeks after the message change to get the real card.
Don't trust the AR-11, they never update your address based on the AR-11. I have sumbitted two AR-11s over the last half year, and the address was still the one that was used for filing I-485. (it's my friend's house, so I still get it).
Good luck.
