Many company moves make sense to me, but I still haven't figured out why Sigma is still producing their Foveon-based SLR bodies, or for that matter any SLR bodies of their own.

Do they believe they will eventually win substantial market share in SLR bodies with so many stronger players? Do they mainly want to hang on to potentially valuable patents in case of industry contraction? Is there a solid future for the Foveon sensor, and is this the best way to use it?

I'm not knocking Sigma here. I think they are arguably the most successful of the independent lens makers and as such can probably continue making a decent living. But what precisely is the value derived from making their own SLR lineup?

Someone please help me understand this one.
