According to the official line:
"NATIVE INSTRUMENTS' experience in developing award-winning music software will be combined with the world-class quality, breadth and diversity of the EAST WEST and ZERO-G sample libraries. A new generation of realism, playability, user-customization and variety in sample-based instruments will be born."
What with rumours of a Clavia/NI collaboration currently circulating, looks like the Natives are making a big play for world domination of the virtual instrument market, and good luck to 'em!
