Employment Based Greencard

Hey,

I have been using this site to try and determine what would happen in my case, but from what I can tell it's a bit random what happens in each case, or at least not clear. To those that have received their GC approvals congrats!

My case is as follows,
EB2, Texas service Center

07/22/16 - I-140 and I-485 filled together
07/25/16 - I-140 and I-485 received
08/12/16 - I140 Premium processing filled
08/26/16 - I-140 approved with Premium processing
10/10/16 - Biomertics Done
10/13/16 - EAD/AP Approved
10/27/16 - EAD/AP Card received
01/11/17 - Texas Center processing dates showing I-485 employment based date of 07/28 (has not changesd since)
01/12/17 - Submitted inquiry on taking longer than processing time
01/27/17 - Received Inquiry response, saying case is currently in line for processing and adjudication.

Issues that may be complicating my case, though the lawyer says it shouldn't be:
- Delayed Biometrics due to Wife and son being out of country and could not file their I-485 until their return
- When they returned in August USCIS placed a backlog on I-485 and wife and son could not file until October 1st
10/3/16 - Wife and son's I-485 received
late October/Eraly November - Wife and Son's Biometrics
12/14/17 - Wife and Son's EAD/AP approved
01/03/17 - Wife and son's EAD/AP cards received

Anyone know of similar cases or any updates from Texas center that would help me understand my case???
