Having Bio done in theory is the last step before getting GC. ALthough, we have seen in this forum people getting another RFE without any reason. SOmetimes they just want to be sure how many times u left the country while your application was pending and where. They ask sometimes for copies of RTD if u have used it on the second RFE.
Personally, I did my Bio week and a half ago and I got approved 5 days later and two days after the aproval notice online it said that my GC has been sent already. What is weird is that I applied with all my family together and so far I am the only one that has been approved. Sometiems they process cases at random. Don't worry man...u are almost there. I am pretty sure that before september 15 u will here good news!...just be prepare, have beers in your fridge for the celebration.
Cheerssss!!
