I want it in a country of which the hosts stand a realistic chance of winning it, so that's Germany, England, or Brazil.
I read that Pele thought that the state of the Brazilians stadiums is awful and the WC should not be held there, so that leaves England and Germany as my favourite candidates.
England had Euro 96, but the new Wembley stadium looks promisingly spectacular, but Germany has great stadiums too. I wouldn't mind in which of the 2 it would be.
Hopefully not South Africa, they just stand a chance of winning it, and with the 2002 going to Asia, 2006 should go back to Europe, European nations are the driving force behind world soccer, so a European nation should host the WC at least ever 8 yrs I think, most nations stand a realistic chance of winning too.
