I was pleased to see this article as I have the same concerns having seen the multi-core intels in taiwan, I have some worries as to what will have the sheer grunt to replace the Quad G5.
While they suspest quad dual cores, I suspect a dual quad core is more likely. But finding a replacement for the quad g5 will be hard. I suspect the quad G5 will be around into next year when adobe finally get photoshop cs into a universal binary.
WWDC isn't that far away, and I guess the rumor season is coming back on line.
