Assuming Scenario 1 will happen (as if it will ever happen, which I think is impossible), these might have been the stadiums.
In Group A, we have the one and only ArenA in Amsterdam, alongside venues in Dakar and Guayaquil. All three countries would be first-time hosts.
In Group B are three legendary venues, two of which hosted the World Cup Final (one did so in its original incarnation). I would expect to hear some loud singing of the Welsh national anthem from the Welsh fans. Meanwhile, with the Rose Bowl, I would've chosen Atlanta, New York, or even Ann Arbor (just imagine the atmosphere of a World Cup game at Michigan Stadium in front of over 100,000 fans!), but I ultimately chose perhaps the most legendary ground in America.
In Group C, we also have some legends, with legendary players playing in them. Could Messi, Ochoa, and Lewandowski please their fans?
In Group D, we obviously have the home stadium of the world champions, which also won at the same stadium in 1998. Meanwhile, the Socceroos could pull off with a big win at their most notable ground as they did in 2005 against Uruguay.
In Group E lies two historic stadiums, playing host to some of the game's most legendary stars. Meanwhile, Saitama would be honoured to have World Cup hosting duties as they did in 2002.
In Group F are some not-so-well-known venues. Despite this, I'd still have the chance to fly all the way to Vancouver to watch my country play in the World Cup after 36 long years. But hey, what can you do? This is a what if scenario, after all. It will not happen ever, unless FIFA somehow makes that decision.
In Group E, the one and only
Maracanã is back eight years after hosting the 2014 World Cup Final and six years after the Olympics. Meanwhile, Belgrade could be seeing some unbelievable atmosphere, while
Yaoundé, just months after the 2022 AFCON Final, would already be hosting significant games.
And finally, in Group H, the World Cup is back in Uruguay after 96 years! It has also been 20 years since Seoul last saw World Cup action. Meanwhile, Ronaldo would be thrilled to play in front of his home fans, especially when they shout "SIUUUUUUU!!!"
Again, this is only a what if scenario. And the most unrealistic of the three I mentioned.
