It seems as if NI is now marketing Maschine Expansions as just "Expansions", and making them available to anyone. I've always known that all of the samples were .wav. As a matter of fact, I've used Prospect Haze samples directly in Ableton Live several times, but now the move by NI is to market them to the masses. I guess it's a good move by them to create revenue. It really doesn't mean much to me. I think I own every Maschine Expansion any way.
