AMD is preparing its new QuadCore solution with the intent to fight back against the Core Duo CPU line from Intel (currently AMD does not have a sensible QuadCore solution, while Intel QX6800 is nearly alone on the high-end market). The code name is Barcelona. It should come out in the middle of the year (before Summer?).
What should Intel do? They decided to start removing from AMD any chance to draw a profit out of it: On April 22, they start cutting prices down -as much as 40% cut on the quad-cores. They intend to make it difficult for AMD to come back in the game.
End-customers will probably see plenty of opportunities appearing as soon as AMD products are out. And the prices will be attracting too.
