I disagree, but it doesn't really matter. The hottest, fastest chip in the world does you no good at all if your supplier can't make enough of them for you to sell to everyone who wants one. And it doesn't help when you make your best customer look like a fool for promising 3 GHz chips you can't deliver ;)
3ghz? xbox 360 3 core cpu is 3.2 ghz....
They are already there...
