I can say this now the AB's are world champs. I've said this many times.
Winning a WC is like rolling the dice, its nothing to do with form or who is the best team, rule books and form go out the window. Talking now about who will win the WC in ~9-10 months time is pointless.
you can talk about form and history going into the quarter finals then it all goes out the window. Heck SA won in 07 without having to play NZ, AUS or France and the biggest threat they had was from Samoa in the pool phase? >.<
France have shown again and again they have a big game in them and despite form and history they can beat anyone anywhere.
a Three test series with a build up and different refs shorts out who's best, one off knock out games in WC's which seem to have their own rule book no one has access too are another matter. may as well toss a coin.
in 2011 france were smashed by NZ in pool phase, struggled to beat, looked rubbish and couldn't even score a try against a 14 man welsh side and then went to push NZ harder than any side in the world could have on that day and had a couple of chances to win.
