I think it's inevitable that the Six Nations will be opened up, the only question is when. The performance of every minnow at this RWC, when even Namibia or Uruguay were able to compete much better than expected, can no longer be ignored.
Sadly, that may be wishful thinking. You only have to look at the voting structure of World Rugby (16 votes for the 'big eight', 12 votes for the rest of the world) to realise that the established countries are chiefly concerned with protecting their own interests.
That said, there is a groundswell of opinion - judging by social media - that the existing 6N should expand to include other nations.
The challenge for the European 'minnows' is to come up with a structure that would allow this to happen. The obstacles include:
1. 6N fixtures currently take place when countries like George and Romania are on a winter break. Italy were included in the tournament in 2000 because they have no winter break. So for 6N countries, an expanded competition would mean significant changes to their season. Matches would have to be played during the autumn (when they have lucrative fixtures against teams from the RC) and spring.
2. Potential loss of revenue. Some have suggested a relegation play-off between the bottom 6N and the winner of the ENC. No way would Scotland, for example, countenance the possibility of playing in a 'second division' of European rugby as their revenue would drop off a cliff. This would be less of a threat if the 'top division' was expanded to eight or 10 or even 12 teams, split into two groups, but that would mean the loss of traditional annual fixtures and more fixtures against countries who are not a 'box office' attraction - which again, means loss of revenue.
3. 6N concerns about standards of the 'minnows'. Personally I think this is a flimsy excuse, and as the WC has showed, when the the 'minnows' have time together as a squad and exposure to higher playing standards, they can be more than competitive.
I think the best answer would be a top division of 10 teams, split into two groups of five, which would address the obstacles above:
- Group matches would be played in the autumn and spring, with semi-finals and final played over consecutive weekends at the end of the season, possibly staged in one European city.
- With five-team groups, and every team having a weekend off, this would allow 'cross-group' friendly fixtures, allowing traditional fixtures to be maintained. The existing 6N would also have the option of arranging friendly fixtures during the winter months.
- Bottom teams in each group would have a relegation/promotion play-off against the top teams from the division below.
- European rugby is just about competitive enough to sustain 10 teams in the top division, without any ludicrously lop-sided results, and standards would improve over time.
- The competition might work better spread over two seasons, but traditionalists may want it to stay as a single season tournament.
Anyway, that's one vision of the future. But what is important is for the 'minnows' to come together and articulate a vision which they all agree on and can present to World Rugby and the 6N with one coherent voice. That is vital. Also, the time to do it is now while the RWC is still fresh in the memory.
