I agree, There is still a long time to begins World Cup. Many things can be happen and will change during this time.
Actually it seems to me there are few groups which have more potentiality to get the World cup 2022. In my opinion, we will get the winning team of 2022 from Group C, Group E, Group G and Group H. Specifically, Argentina, Spain, Germany, Brazil and Portugal are very promising.
Along with the countries you have listed, I would add Belgium and France as well. I would rate them ahead of Portugal, because the latter is entirely dependent on one player. For me, Argentina and Brazil are having the maximum chances, but some of the UEFA nations are quite capable as well. But then, international football is very unpredictable. Who in their wildest dreams might have thought that Croatia would reach the final of 2018 World Cup? It will be real fun, if such a lower ranked team manages to reach the finals this time.
learned from the previous edition of the world cup where many strong teams had to fall early such as Brazil, which was defeated by Belgium and also Argentina, which was eliminated by France in the round of 16, but for the Qatar world cup this time they are still the seeded team who I am the favorite to win the world cup title without underestimating teams like Portugal, Belgium and Argentina, but I prefer France to defend the title they won last season considering that the material that France currently has is of equal quality in every line, however anything can happen in football where many bottom teams or dark horse teams get rid of the subscription to world champions this is what is called football where it is full of drama and existence
