Many sources (news.com, Slashdot) write about Apple switching from IMB PowerPC processors to Intel.
If it's true, not Job's bluff, it's a huge risk for Apple. First, not all software will work on new processor (the system will as Mac OSX is based on BSD). Second, it means Mac OS on Intel and non-Apple hardware (less profits from computer sale). Very interesing. It'a also a move from 'cleaner' architecture to compatibility mess of Intel chips.
