I thought the 2011 10-speed mechs (new logos) went over to the same cable pull as 11-speed? 2010 have the same pull.
I can't even begin to get my head around why you think this would be the case? The spacing between 10-speed and 11-speed is different, so they must have different amounts of cable pull, otherwise you'd never get the gears to index properly.
As I understand it, all 10 speed components are compatible with one another. I've got 2010 Centaur levers, in the new shape, working with a 2006 (or maybe earlier) Centaur rear mech without any issues.
