That's a tough question to answer. The big game studios, for the most part, focus on console titles simply because console titles are wins, economically. They are harder to pirate, etc. Even id Software considers the PC a secondary platform, which does not bode well for Mac gaming. If you are only going to reach a minuscule number of customers, why spent the effort putting out a Mac version of the software? I have no idea how the smaller game studios view the Mac, however keep in mind that the iPhone and Mac are very different platforms, and games that work well on a phone may not translate well as a desktop gaming experience, especially considering what people expect of their games in this day and age.
