Interesting. During the Psystar case, I wondered whether Apple would ever be able to get Intel to make special versions of processors that it could somehow tie Mac OS to, instead of having to sue the clone makers. Perhaps this is the start of Apple moving in that direction?
Suing Psystar is a lot cheaper and a lot more satisfying than having a special version of the Intel processors. And remember that MacOS X probably up to 10.8 would have to run on current processors, so switching to an incompatible processor wouldn't gain anything.
