Without an official comment from Google, I guess we'll never know for sure. But I agree with you - we were supposed to see a 1-2 punch with the Scraper Update and the Farmer Update. Right now, the first punch seems like it missed it's target pretty badly. Several gains even seems to have been partially wiped out by the second punch.
If these two updates are somehow technically in conflict right now, then we could hope for a real improvement in the scraper area soon.
