Production Grooves: EZ Drummer mapping?

I just upgraded from 7 to 9 and have been watching all the new feature videos from 7.5 onward.

The Production Grooves library in 9 looks interesting. I use EZ Drummer for songwriting sketches, which of course has its own library of drum loops. Has anyone who uses EZ Drummer worked with the Production Grooves feature? I’m wondering if they map to EZ Drummer by default or if we’ll have to go through and set up a drum map to point PG to EZD.

Either way, looks like another handy batch of stuff to have at hand.
