That is pretty cool. And it does make sense if they can use up extra capacity. I think it would also be useful for them in extending the life of older manufacturing lines. Not everything is needed on 32 nm for example. It's also a step to opening up another future potential - the open source CPU. I still think there is good room developing for an open source or even crowd sourced processor design. Something that multiple parties contribute to (like ARM) but for which the license cost is minimal or non-existent. Imagine being able to order a generic CPU type, or for that matter being able to custom build your own specifications. For example I've always wondered what would happen with a pretty generic CPU paired with a massive cache. Just one idea, I'm sure there are thousands of others out there.
