The only shift I can imagine happening is that some CPC publishers will shift to CPA, as the overhead associated with evaluating the various affiliate brokers and opening accounts, etc, just got eliminated, as the publishers already have an existing relationship with Google.
"Affiliate marketing networks like Commission Junction and LinkShare are screwed. These networks also operate on a cost-per-action basis, mostly with online retailers. Even though some of them have scale, they will not have the ability to compete with Google on sheer size of network."
