But it takes a lot of silicon to do what NVIDIA and ATI are doing today on their chips, and merging CPUs and GPUs will not be a matter of simply gluing the together. There will be tradeoffs in things like capabilities and power budgets between the two, with the potential for different chip personalities for system builders to select from

The only company publicly working on fielding something right now is AMD with their Fusion architecture, and that is only targeted at consumers right now. Everyone in the high end community wants to know when the other shoe will drop. From the tone of Freuhe’s post, it won’t be soon...
