The span of six weeks from mid-June to mid-July is my favourite time of year. Even the most ardent northern hemisphere rugby fan must admit the Tri Nations competition represents simply the best rugby in the world.

Still, the next two weeks will provide a preview to possible matches in the Rugby World Cup knockout round this October.

This Saturday, the top four southern hemisphere teams in the IRB rankings will host their counterparts in the northern hemisphere with New Zealand (1) v. France (2); Australia (3) v. Wales (8); South Africa (4) v. England (7); and Argentina (6) v. Ireland (5). The following week, the All Blacks will face France for a second Test, while Australia will host Fiji, South Africa will face Samoa and Argentina will battle Italy.

Among the hosts, I predict South Africa to display the best form and would expect them to go into the Tri Nations competition as the team to beat. England would need to play a virtually error-free match to come out on top, but I pick the Springboks to win by at least 15 points. Against Samoa, look for a winning margin of closer to 25 points.

While I would still choose the All Blacks if I had to pick a winner of the World Cup later this year, they are still a few weeks away from their top form. I have a feeling that both Tests against France will be up for grabs up to full time and I think France will steal a victory in Auckland but fall to a re-energised All Black side in Hamilton the following week.

Australia are not playing up to their potential of late, but they should come away with victories against Wales and Fiji, though perhaps with more effort than they will expect. The Wallabies will hold on, but both challengers should stay within a try or two of upsetting their hosts.

Although Ireland have a number of star players, I pick Argentina pulling out a narrow victory in a preview of their September 30 meeting in Paris that will likely decide which of the two advances to the quarter-finals from Pool D. Argentina should follow next Saturday with a more decisive victory against Italy by at least 10 points.

While it might seem as though the World Cup is far off, the next several weeks will give us a good glimpse into the future. Not a perfect crystal ball, perhaps, but as close as we will get.
