Chris Rattue: Samoa v Scotland. I've got a strange feeling the Scots will get up and win it in Newcastle having been battle-hardened against the Springboks.
Nigel Yalden: Italy upsetting France in Pool B with an un-Italian display of consistency over 80 minutes, thus leading to the Azzuri, not Les Tricolores playing the All Blacks in the quarter-finals.
Williams: I think that Fiji will beat either England or Wales in pool play.
Gray: Samoa will bring all the devil they brought to their work against the All Blacks in Apia this year and upset the Scots.
McKendry: Fiji to beat England in the tournament opener - partly because of the hype and pressure on the hosts to deliver the perfect start and partly because of danger man Nadolo.
Which major nation will miss the semifinals?
Paul: England. They aren't going to get out of their pool.
Marshall: England. I see them qualifying second out of there pool and then exiting in the quarter-finals.
Rattue: Depends on the definition of a major nation. To make this easy - Wales. They are disintegrating, partly through major backline injuries.
Yalden: South Africa. Despite winning Pool B, the lack of playing time for their returning stars will be exposed in a quarter-final loss to hosts England.
Williams: Australia, because they won't get as many points as their opposition in the quarter finals.
Gray: The Wallabies are getting a bit too brash about their resurgence. A series of tough games will nobble that confidence and their player depth.
McKendry: France - beaten by the All Blacks in a nervy quarter-final in Cardiff.
What are you most nervous about with the All Blacks?
Paul: South Africa remain the side with the greatest capacity to beat the All Blacks in a one-off test. The fact they are having a disrupted buildup may benefit them - bring them tighter together.
Marshall: Making sure they manage the pool games so they hit the quarter-finals with individuals and the team absolutely firing.
Rattue: Just the usual nerves times 10, which is what World Cups should be all about.
Yalden: A spate of injuries in the forwards.
Williams: For me, the biggest challenge is the urge to play attractive rugby. When in tournament's like this, it's all about reading the situation and playing to win.
Gray: Food poisoning, dodgy detergent in their washing, boredom from easy pool games, flat tyre on their bus on the M4, smothering attention from the travelling fans...
McKendry: Predictability. They were found out by the Wallabies in Sydney recently, thanks partly to their insistence on shifting the ball sideways and partly because of the Aussie linespeed on defence. In the end it cost them the Rugby Championship.
