I'm just wondering if this CPU/GPU integration will ever turn into anything more exciting than glorified IGPs.. More 'talking' between the CPU and GPU, perhaps using the GPU as a generic floating point accelerator when not doing graphics, or using it for physics/etc and using a discrete add-in board for graphics..

Are they planning anything like that for Westmere+Larrabee, or will it be just like AMD's 'Fusion', boring old IGP on-die?
