With the release of Service Pack 1, you get two new features in Central Admin (among other preceding CUs as outlined here).
The first one is OneDrive for business integration. This allows for you to redirect users to the cloud for their ‘personal’ storage. This can be done for everyone OR you can select specific audiences. This allows for a dynamic approach for moving certain users to the cloud. For instance, I can make all of my support services staff use the default On-Premises storage and I can redirect my Sales users to the cloud to allow them to have easy access and Office Web Apps integration built in. This of course will include the new Yammer social integration features when they are released near the end of this year or early next year. OneDrive for business requires an additional license and early indicators seem to be anywhere from $2.50-$5.00 per user(?).
You can also redirect the Sites suite link. This will show users sites they follow for SPO only. They will no longer see any On-Premises sites that they are following. This is an all or nothing option as well.
