Probably depends on if it sells well for the PC. However, Doesn't seem like Disney is much of a Mac developer except for kid's educational software.
On a related tangent... it drives me nuts when movies which rely on macs for part of their creation of special effects (example - Lord of the Rings, Hulk, etc) have spin-off games that NEVER GET PORTED! Not that I care much about The Hulk - its just annoying.
