Bro,
I believe all VO should complete their all pending file process from 2011 by within end of Dec'15 due to EE and that should be more expedite, speedup, clean systematic etc. process from each and every sector from 2016.
So that all VO are working hard to complete it by their professionalism without any mistake otherwise they need to pay huge amount of loss for any mistake for PR visa process.
Your file also in the list and that is continue to update from various sector issues.
Only my curious from your one point : Status: Review Required form your latest GCMS note. Need to find out what does it mean there.....
Yes brother I am also wondering what they will be doing for this Review.
