The information is already public in the form of the system requirements page. Anyone adopting new software should be reviewing that first off before any money changes hands.
3DSMAX is in the same position that AutoCAD was several years back. Most, if not all, of the program is built on Windows exclusive technology. In order for a native Mac program to be built, like they did with AutoCAD, they need to strip it down and re-engineer the guts to be system independent with an OS-specific user interface layer. Because there are a number of differences between Win and Mac (including development and UI paradigms) we'd end up with similar results - a slightly different interface (with users demanding that they be identical); certain features not available in the Mac version, whether due to requiring more development time or simply not supported in the Mac environment (and further demands that they "just make it work"); and more than likely some serious limitations in scripting/API/customization.
All that is driven from expected return on investment. Will there be enough uptake from Mac users to pay off the required development? Will there be enough ongoing support to continue to support both version?
