When I think I've found an example of brand domination, it often goes back to backlink strength in the final analysis.
Tedster, anything significant you see in the “backlink strength” of these branded sites that appear to have gotten the Vince boost? Despite Google’s denials to the contrary, the more we look at it, if it walks like a duck, and quacks like a duck, it’s a duck. Many branded sites rose in ranking, during a specific time frame (or the non branded sank however you prefer).
I’m a believer that when it comes to upper echelon sites in Google, back links pretty much determine where you rank. So, to your point if it is back links, what changed relative to the types of links that point to these branded sites? If it’s the links, some added weight must have been given to something about them. (or back link profiles of non branded sites became less significant)
Something changed relative to many branded sites, and where they rank, around the same time.
It may well be one of those "start with a hand picked seed set and learn from there" metrics. If I were trying to reverse engineer this change, I'd look at the types of sites in a domain's backlink profile for some kind of a trust and/or authority factor. Established brands are usually going to have a kind of breadth and diverstiy of trusted link citations in their backlink profile, and on the websgraph they're going to be closer to other sites of the same type.
