I saw a demo of this a while ago and the objects are not pre-fractured. The System does it all in real time. Of course, there is a plug-in for Maya and Max coming out (or out already), so I hope DOPs won't lose a lot of it's “uniqueness”.
This does raise the bar for Houdini to support some sort of Automatic or Semi-Automatic Fracturing.
Cheers,
