Who Are Bentley’s Knowledge Executives?

Back in July this year this article http://communities.bentley.com/communities/other_communities/b/bentley_communities_blog/archive/2014/12/22/who-are-bentley-s-knowledge-executives mentioned that Knowledge Executives would be announced. Unless I have missed it I haven't seen the announcement. have there been any new Knowledge Executives? If so who are they?
