My predictions for top 10:
1
2
3
4
5
6
7
8
9
10
gets first position at the medal table since 2004, so their place is secured, but is back (as RPC of course) with probably their best team ever (?), so I expect them to "steal" some of the golds other big nations won in their 2016 absence. They'll have a good fight with , which since 2000 always figure in the top 3 positions, and this time maybe can even maintain the second place.
About and it could go either way, both are very consistent and finish at the top 5 in almost every recent edition. I gave United States the edge because Ukraine has fewer athletes this time. I could change the order of the top 5 nations, but for me this are the most likely to end ahead of the competition.
could potentially challenge for top 5 as they have a good variety of medalling sports, but their results in Athletics and Swimming (obviously the two sports that give most medals) aren't that great. Either way, they should at least get 6th place ahead of , , and which are close in medal chances. Netherlands is strong in Cycling and Swimming, Italy in Swimming (amazing results at the most recent world championships), Germany in Cycling and Athletics, and Brazil in a few sports. I think Netherlands will pull ahead because they are clearly in an ascending curve when it comes to Paralympics, but Brazil could challenge for 8th and show the "legacy" of the Rio Games.
A slew of nations could challenge for top 10 though. was top 10 in the last two editions and of course could repeat the feat. is consistent and could show the improvement ahead of their own Games. , , , , and didn't reach the top 10 in London and Rio, but with some luck at the gold medal count maybe will. And of course there's which didn't get a single gold medal in Rio and it's in a decline since their best result in 2004. The addition of new sports should help a little, but I wouldn't be surprised if they don't reach top 10 (the first hosts since Greece to do so). I really don't know what to expect from them but maybe they'll do amazing like at the Olympics.
