I can't speak for Cakewalk, of course. But the Mac DAW market strikes me as a tough landscape to make money in. Logic and ProTools utterly dominate, Garage Band has it sewn up for hobbyists, and Apple can fight, and has fought, a far tougher price war there than any other developer. So I can well imagine the proposal not surviving a serious profit-and-loss study.
They are still losing in the desktop market. The amount of PCs used on a planet makes Apple still quite minimal. Remember they are a hardware company.
Imagine if Logic was released for PC? MOTU's DP is now cross platform.
Sony has ventured into Mac land with audio and some are hoping they do that with video.
If a company begins cross development, more resources would have to go to the Mac side. Updates are more frequent for a Mac OS.
Bootcamp is always an option. Live 8 users found that Live worked better on Bootcamp/W7 than their Mac OS.
