I hope that this means a Dothan-supporting motherboard with Dual Channel, fully functional locks, and most of all, rich memory latency and overclocking features!
A Dothan machine with dual channel, PCI-Express (SLI), and a high FSB would be incredible - enough to make me buy an intel machine.
Unfortunately, I cannot see this product becoming widely available. More likely this will be an extra that will ship with some ASUS products, or that will be available in limited quantities.
In that vein, given the very low demand for such an adaptor, the functionality of this will probably not be the best: there are often compatibility issues and general problems with things like this, especially when there is a low demand for the product.
