Paul:
Never mind the 'World Series' getting another nation. The 'Six Nations' could do with another Northern Hemisphere (European?) team. At present it is a little unfair that each season three of the teams get the advantage of playing at 'home' 3 times while the other 3 teams only get two 'home' games.
Maybe, if we can't find a seventh nation, things should be evened up by playing two home games, two away games, and one at a neutral venue!
