AMD is working on getting cash fusions before they can implement the actual fusions. Their plant in Dresden iirc is being sold to TSMC and then they, like Nvidia, will be customers. AMD will move their Athlon and Opteron cpu production probably solely to Texas and Taiwan plants. They will contract IBM to also help produce more chips for them, probably in New York/New Jersey and they will center their main cash flow around integrated chips and mass market consumer electronics.
Then they will start massive price cuts to drop the prices of their products which in turn limits the commercial success of their competitors. Remember, if AMD/Nvidia/Intel sell a product for 250 dollars and slash prices to 150 dollars the next month its easy to see they built acceptable return + a buffer to cover future price slashes. If AMD can push Nvidia to keep prices low on new to market goods then Nvidia cannot recoop that buffer.
This is business. AMD is positioning themselves to be the dominant entity. They will force Intel's IGP's in the future with Fusion. You will always be able to upgrade your graphics, even with Fusion, but when you can sell a IGP that requires nothing more than CPU SKU's to improve performance that puts Intel in a bad position.
Think what you want about AMD they are shrewed mf'ers.
