A few quick points:
Intel is not interested in making PPC's. Microsoft LEFT intel for a reason, they wanted to own the chip design and farm out production to Cheaper fabs. Intel does not equal cheaper fabs. Intel will not get a bulk or part of the sales on the next gen consoles. I am fairly confident Microsoft went to Intel first and foremost for its next gen console. Intel had a leg up at that point, if they wanted the business that badly, they would have it. End of story. Why lose it there, go in a huge roundabout way to get it back? Makes Zero sense. Also note, all these "badass" Next gen consoles are much closer to embedded CPU's than to a G4/G5. They are dumbed down and highly optomized, not much different than the powerpc's that most likely run your car.
Anyone who says they will stop using a mac if it has an X86 chip / Intel chip (Some people even contradict themselves by saying it would be ok if it were an intel chip, but NOT x86?!), whatever. Thats about the stupidest statement one can make. If that is what you base your computer purchase's on, then you need some serious help.
Another point is that most likely the leaks are not coming from the "apple" side, but from the Intel. That would explain the lack of info through normal apple outlets.
To anyone who thinks this is a "ploy" to get at moles, or a way to tell IBM they are not happy with their performance. Hello, this is the real world, with big boy company's, with real people. Do you not think SJ can't get on the phone with IBM and express displeasure with their performance? Do you think he has to do it in a way like this? He is IBM's CUSTOMER. He can call them, and express displeasure, and say "Fix it, or im gone". He does not need to create elaborate ruse's etc. Don't think that he has not confronted IBM and motorola. It has happened.
Whether this happens or not is still in the air until tommorrow.
However, if it does, (and it looks likely based on some VERY trustworthy sources putting their necks on the line), you had better believe Apple has done everything POSSIBLE to make the transition seamless and smooth. Will sales tank? Possibly, but anyone who believes that a major corporation has no idea in these things had better reconsider. They probably have simulations down to the DAY of what will happen sales wise / etc. Don't think they don't.
