The only one I've found myself so far is: http://leanbrandbook.com/
That is also in the pre-order stage right now, so I ordered that since it does claim to have a framework and language.
Since you've spoken on Lean UX, I'm curious to know your impression of what Lean Branding could have over The Lean Brand.
Have you read an advanced reading copy of either book?

I wish your talk was available by video, yeah. I've gone through it though. Well done!
It seems like Lean Branding ( the book ) and your talk on Lean Branding seem to have a different definition of Brand than The Lean Brand and Bill Beard do ( only lightly reading through Beard so far ) ... the difference being Brand as Relationship and Brand as Identity.
But as I go through your talk, you seem to use a lot of the same terminology as The Lean Brand, and have the same core focus, compared to Lean Branding.
