Regardless of flow, Parker would never merge envoy, PSA, or PDT. He is all about the divide and conquer whipsaw game. When you watch him talk about the regional carriers during the townhall meetings he is very proud of his ability to pit the regional carriers against each other. Not just in compensation but on performance matters as well. Maybe if AAG bought another carrier, I could maybe see him merge PDT with them but even then, I wouldn't be surprised if he didn't and kept it at 4 wholly owned.
