No, they are specifically for EZDrummer. Superior 2.0 is supposed to be on the way but no one is dropping any hints whatsoever about what's in it. I wouldn't be too surprised if some of these new kits were included though... but that's totally unfounded speculation on my part though!
Actually, there is a veritable stack of midi files distributed with Nashville. A huge array of shuffle grooves for one. Nashville is a superb expansion pack for EZdrummer IMO with a great room sound and I would happily use it on a wide range of styles.
