No one has responded because no one knows. If it isn't public knowledge out there on the interwebs, you won't hear anything about it here either. What I would really get excited about is if they make easily replaceable pedal bodies to go over the spindle so that I can go between my MTB and Tri bike easily just by swapping the pedals and sliding the new pedal body on. The difference between Look style cleats and SPD-SL is not really noticeable to me so I'm not too interested in that.
