The EKAR rear derailleur WILL NOT work with a 12/11/10 speed rear shifter. They are not designed the same. One is a 2d geometry and one is 3d geometry. I should've mentioned this in the questions/answers post I did. Sorry. This comment(will not work) is from Campy directly. I have not tried it. No reason for me to try it right now.
EKAR is stand alone for now. I have no info on a 13 speed road kit. I don't think they could do it though. 130mm rear spacing, I don't see how they could cram 13 in there. 12 is pushing it now.
