On Wednesday the teams that finished in the top three of their Pool at the 2015 tournament - Argentina, Australia, England, France, Georgia, Ireland, Italy, Japan, New Zealand, Scotland, South Africa, and Wales - will be placed in one of three "pots" according to their current world ranking. The four highest-ranked teams go into Pot 1, those ranked 5-8 into Pot 2, and those ranked 9-12 Pot 3. Pots 4 & 5 will comprise the yet-to-be-determined Regional qualifiers with each Pool comprising a team from each Pot. November International & Six Nations results have seen South Africa drop into Pot 2 and Argentina Pot 3, which increases the likelihood of at least one 2015-style "Pool of Death", especially as none of the Pacific nations, who traditionally trouble Northern Hemisphere opposition come RWC time, are seeded but all three are likely to qualify by one means or another. Pot 1 New Zealand England Australia Ireland Pot 2 Scotland France South Africa Wales Pot 3 Argentina Japan Georgia Italy As noted above, the remaining eight positions will be determined by a series of regional and inter-regional qualifiers, and a four-team repechage. All 20 qualifiers will be known by November 2018.
