Eleven bids were submitted in 2009, covering 13 nations, with two joint bids: Belgium-Netherlands and Portugal-Spain. Mexico also submitted a bid, but withdrew theirs in 2009, while Indonesia had their bid rejected for lack of government support.
For 2018 and 2022
FIFA President Sepp Blatter has said he would welcome a 2018 bid from "the homeland of football." England has previously hosted the 1966 World Cup which it won and Euro '96, as well as previously bidding for the 2006 World Cup. Should England succeed, it would be the sixth nation to host the World Cup for a second time.
With all good audience results, soccer gaining more popularity and supported by the financial and attendance records of previous hosted 1994 FIFA World Cup, the United States are going to be a big England's competitor for the 2018 bidding. The US Soccer has submitted two bids: one for 2018 and in case they don't get it, another for 2022. The 18 host cities were already chosen: Atlanta, Baltimore, Boston, Dallas, Denver, Houston, Indianapolis, Kansas City, Los Angeles, Miami, Nashville, New York, Philadelphia, Phoenix, San Diego, Seattle, Tampa, and Washington DC.
Russia comes strong for the bidding due to the FIFA's rotation policy. However, they are not as well structured as the USA and England, but the country is ready to spend some $10 billion on the tournament, especially to build stadiums following FIFA standards. Russia hopes to have five stadiums fit to host World Cup matches ready by 2013, which will be used for the 2014 Winter Olympics.
The joint-venture consists in Spain leading a 12-stadium project with eight of the venues, and the opening and final games would be held in Lisbon and Madrid, respectively. Spain has previously hosted the 1982 World Cup, while Portugal organized the Euro 2004. If the Portuguese-Spanish joint bid succeeds, Spain would become the sixth nation to host the World Cup for a second time.
Using the same model as per Portugal and Spain, Belgium and Netherlands would share the building of stadiums which comply with FIFA standards. Luxembourg will also help in the World Cup organization in case the bid is the winner, however it will not host any game neither be automatically qualified for the event.
For 2022 only
Initially Australia confirmed a bid for 2018, which was eventually withdrew months later. One possible stumbling block to the bid is that almost all of Australia's largest stadiums are used by other major Australian sports (Australian Football and Rugby) whose domestic seasons overlap with the World Cup. Australia has hosted several tournaments: U-20 Soccer World Cup, 2000 Summer Olympics, 2003 Rugby World Cup among others.
Japan is bidding to become the first Asian country to host the World Cup twice; they co-host the 2002 World Cup with South Korea. They have also withdrew the bid for 2018 and analysts say that their chances for 2022 are very low as well.
As their previous partner of 2002 World Cup, South Korea has put forth an offer to host the 2022 edition. Due to the rotation policy and FIFA willing to take soccer to places that it needs to be developed, the likelihood is not good for South Korea's (and Japan's) bid.
Qatar is attempting to become the first Arab nation to host the World Cup. Qatar is planning to promote this bid as an Arab unity bid and hope to draw on support from the entire Arab world, and are positioning this as an opportunity to bridge the gap between the Arab and Western worlds. Some concerns with Qatar's bid deal with the extreme temperatures especially in June and July, but according to them, this is not a problem at all, stadiums with controlled temperature will be built, once they win the bid for 2022.
Canada Soccer Association was also willing to pull together a bid for 2022 edition. With the expectation that the United States will land the 2018 or 2022 event, while other continents will also get to host it as it rotates from one region to another, they decided that it does not worth to move forward with an official bid. However, the 2015 Women's World Cup is more likely.
Whether Canada's chances to host or not a World Cup is low, I do hope see Canada team being part of the 32 nations in Brazil 2014.
