The United States withdrew its bid to host the 2018 World Cup in order to focus on the 2022 finals. That means two things. One, that Europe is guaranteed to host the 2018 World Cup (England, Russia, Netherlands/Belgium, and Spain/Portugal are the only remaining bidders). And two, that the US will likely get the 2022 World Cup, which is fantastic. Granted, the latter is only my speculation because I don’t think the US would withdraw unless it got Europe’s support. Then again, since Europe is now competing against itself, who knows if there was a deal made (I do think the US will support England for 2018, with the reverse being true for 2022).
So, what of 2022? The remaining bidders, other than the US, are Australia, Japan, Qatar, and South Korea. Of those, I think Japan and South Korea are longshots at best, simply because they hosted the World Cup in 2002. Australia may or may not have the stadiums (there are five with capacities over 45,000 and eight between 20,000 and 31,000). The weather will be fine, though, which is nice.
I figure Qatar will be the main competition, if only because of the money it has. The problem is the temperature, which is about 50 degrees Celsius (122 degrees Fahrenheit), during the World Cup. That will necessitate covered stadiums, or very odd game times. Speaking of stadiums, there is only one 50,000 seat stadium in the country, while the others are either 20,000 or 25,000. I still think Qatar will be a serious bidder, but that the US will win out.
