I-797?

I have resorted to asking my dog when he thinks the I-797 will come. So, Charlie, when will the I-797 arrive? This is his standard answer, a little head cocking and blank stare. So, what do all you fellow bloggers think the answer will be? The agency sent the homestudy in on Feb 14th. Anybody got a scope on how long Atlanta is taking? Any juicy news would be appreciated!
