The CBC's 3-anchor scenario sounds like a "reinvention" of ABC's World News Tonight (1978-83) with Frank Reynolds in Washington, Max Robinson in Chicago, and Peter Jennings in London.  3 anchors may be the CBC's way to get Ian Hanomansing as an anchor based in Vancouver since he appears to be uninterested in moving to Toronto (smart guy).  My vote still goes to Diana Swain - after all, it's 2017 so all 3 Canadian network evening news programs should be anchored by women! 
Best wishes for your break and we look forward to your return.
