I have to admit I am amazed at the speed you guys work at. I have been waiting for version 3 of ZBrush for Mac for ages with no hint of a release date.
Too many software producers use the 'works on mac under windows' excuse for not bringing out mac versions of software, but why buy a mac if all your programs have to be run under windows??
Andrew if I could buy shares in your company I would do as I guarantee you will make a fortune out of this (and other) software in the future if you stay commited to it as you have done thus far.
I recommend talking to Newtek about a package release with Lightwave. They often bundle software with Lightwave and as Zbrush costs lots more than 3dcoat and doesn't have native lightwave support I think Newtek would be very interested.
If you are looking for another project to work on try making a realtime 3d engine that works with Macromedia/Adobe Flash. There is no good software that does this at present and the 3d support in Adobe Director is rubbish.
Keep up the good work.
