Excellent question. I'm wondering the same thing. Someone in the AdWords section said Yahoo will keep its best paying advertisers and fill in with Google where there is open inventory or low-paying advertisers. Could maybe mean higher EPC with YPN if some of the dud advertisers leave or are forced out? Of course, with fewer Yahoo advertisers, revenue could also drop.
