Google to become affiliate network host?

Michael Nguyen has a different theory again on what the new Google Wallet might actually be:

I think Google’s initial use of a payment system is to add a pay-per-sale model to their current pay-per-click advertising network. Merchants using AdWords to advertise and Google Wallet to process their sales will be able to track which ads lead directly to sales and at what cost. Merchants will be able to tap into the power of large scale affiliate marketing (ala Commission Junction). Publishers can then choose between which model to promote – AdSense for clicks or AdSense for sales.

May be I should start a book on which rumour turns out to be the correct one :-)
