No, they are from Aureal
while they were in court, they were paying some people to help make drivers, but never really did get too far.
But I'm not certain that these are the latest drivers even, I'm a bit surprised they were leaked.
at vortexofsound.com, david, the webmaster, was beta testing and said there was a NDA in effect, and that Creative got the rights to it, so the drivers could still not be released.
