Tech Crunch reported the soon to be launched "deep integration" of SalesForce and Google which they see as SalesForce selling Google services though their apps.
But the bigger part of a deep integration to me would be the combination of Google Analytics with SalesForce. This integration would allow people to track conversions offline and bring GA current with the most advanced analytics packages that are already doing this, though the ability has been available to manage AdWords accounts from inside SalesForce since last year.
Though Tech Crunch's earlier comments, on the SalesForce partnership started last year, contributes another benefit - Google gets a sales team for the offline apps.
The speculation will be answered when SalesForce makes their announcement Monday.
