Well my opinion about it is it's very similar to Google Affiliate Network. The program was removed from Adsense and created it's own program (Google Affiliate Network). Payment is by CPA (cost per action). CPA still looks like an experimental stage and I don't know if it will replace or affect the CPC of Adsense publishers because obviously it is still Google's main bread and butter.
