If the WCC is to gain any credibility, then it must alternate between England and Australia hosting the games, and be played at the end of the season so both premiers can play with their winning teams and coaches (this way the Poms don't have 2 comps game of practice to our trials).
Better yet, start a champions league type thing (was mentioned a few weeks back on Fox). Take the top 4 from each comp (whomever makes the prelim finals) and have them go at it for the prize. Would be a whole lot more exciting than the four nations.
Oh, and Rus:
