The transition will be easy for applications that rely on Apple's APIs only, the fun will be for programs that use proprietary third party components all of which will need to be rebuilt, as well as all binary plugins to applications. I can imagine this might be a huge job for some of the more heavyweight production programs for Mac , as well as AAA games. It would basically spell doom for Parallels and other virtualization software which give Mac switchers an escape hatch back to any Windows programs they might use.
