I wonder what the speed of a moving filter array exposure might be? Sounds like there could be time for movement between the capture of the R, G & B channels, i.e.: motion smear?
As for Sigma's Foveon, if the problem of poor sensitivity at higher ISO's could be resolved, it might have potential. However, in a recent interview Shri Ramaswami w/ Foveon stated,
"And of course, there are some disadvantages with our approach. Everyone knows our high ISO, for instance, isn't up to the standards of the competition." And he didn't suggest Sigma/Foveon had any remedy for the problem
. In fact it may be physics controlling the process which means it is as good as it gets!?

Gotta love the technological advances (and sometimes the retreats) in the field of photography...
