I just talked with USCIS 2 days ago asking about how long it may take. (in CSC) She told me "normal" processing times right now are at about 6 months.

But, each case varies. I've searched through a lot of the threads here on VJ and the timelines are all unique. Some take 3 months, some a year...Just depends on each individual case. Good luck on your case

Be patient... it is VERY hard. I've been in process for almost ALMOST 3 months exactly. I have no touches nor updates. PATIENCE PATIENCE PATIENCE.
