A few rumors about Aladdin 4D 6.0 have been spreading lately, like it will never ship or has not even been developed yet. We have also caught some flake for developing the Mac OS X version first. We could have cancelled the Aladdin 4D 6.0 project long ago but chose to continue to put resources into it. As far as releasing the OS X version first, this helped to get the code cleaned up and will help fund the other versions. We can't give you a firm shipping date but we had hoped to have the Mac version done by November 30th, 2011 so we are getting closer.
