Although Apple hasn't officially confirmed this, we all know that they have been in development of chips for quite some time now. If this is true, it could be a massive blow for Intel, not just in terms of order declines, but also in terms that if this shift to in-house production turns out to be a good move for Apple, it will encourage other manufacturers to do the same thing. Don't see this as something that can hurt us right now, but if this starts a trend we could suffer terrible consequences in the long run.
