With everybody (including myself) being excited about the new bone and bone deformation features, one might easily forget that you can also rig simple cut-out characters with the new group transformation widget. Here is a basic rig (it has no switch layers for mouth, eyes and hands yet) I constructed without using a bunch of rotation layers and only two exported values (those can increase when you get more complex characters).
Pivot points are accessible via sets.
edit:made with dev version 17 june 2014.
