Looking for anyone in the same boat as me

[joelly]

My case is as the following:

EB2 / RIR / NON-RETROGRESSED COUNTRY
LC APPROVED 9/30/2006
I-140 & I-485 FILED CONCURRENTLY - RD 10/31/2006
BIOMETRICS TAKEN ON 11/18/2006
RFE RECEIVED FOR I-140 ON 1/4/2007 (RESPONSE MAILED ON 2/21/2007)
I-140 - APPROVED 3/5/2007
I-485 PENDING
TEXAS SERVICE CENTER

I'm located in California.
Is there anyone else in this forum that share about the same dates with me?
How soon can I-485 (in my case) get approved?

I appreciate any respond. Thanks in advance!
