World Cup draw and odds - Based on Betfair

I am intrigued on how odds change, so I have provided the odds and draws as per group (taken from Betfair.com on 06/12/13)

So based on the odds, the favourites per group are:- Brazil (4.4), Spain (8.8), Columbia (23), Uruguay (30), France (22), Argentina (6), Germany (7.4), and Belgium (16)

France suppose to have a good draw, and favourite for the group.
England seems to be in a tough draw, as they have not beaten Italy in a competition.

I wonder if the odds will now change based on the draw?
