485 LUD, what does this mean? PJiang and XDJM please!

EB2 NIW, PD 09/2006. My I-485 was transferred to NSC in 09/2007, and my first FP was in 02/2008. There has been no update on I-485 since my first FP until yesterday.

For your reference, I am coping the new status from the USCIS's case status website, Could you please let me know what this means? Many thanks!

Current Status: This case is now pending at the office to which it was transferred.

The I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS was transferred and is now pending standard processing at a USCIS office. You will be notified by mail when a decision is made, or if the office needs something from you.
