Google Wallet hasn't had an easy start. Despite becoming the de facto standard for payment in the Android Market/Google Play Store, its adoption with consumers and retailers for NFC-based payments is effectively nil, with CitiBank and Mastercard being the only non-carrier infrastructure partners of note. The fact that the service has suffered multiple privacy scares and a short feature outage doesn't help. So it's no surprise when Bloomberg reports that Google's top brass is reevaluating their strategy, with the possibility of adding a revenue share system for the carriers that support it.
