My expectations concerning number of medals:
I won't include the newly added sports, because i don't follow them and don't care about them.
Sadly we don't have the "How many athletes of your nation will qualify for the 2020 olympics" thread that we had before the last olympics ... until now, but i guess that's just because we don't know the qualifying procedure until now ... ?
Archery: 1-2 medals (women's team, women's individual)
Athletics: 6-7 medals (1-2 x men's javelin throw, men's discus throw, men's shot put, decathlon, men's pole vault, men's triple jump, men's 20 km race walking, women's 1500 m, women's 5000 m, women's 100 m hurdles, women's 3000 m SC, women's 4 x 100 m, women's long jump, women's shot put, women's discus throw, women's javelin throw, heptathlon)
Badminton: -
Basketball: -
Boxing: 1 medal (On the men's side: Baraou, Harutyunyan, Kadiru)
Canoeing slalom: 2 medals
Canoeing sprint: 6-8 medals
Cycling road: -
Cycling track: 4 medals (1-2 x women's sprint, women's keirin, women's team sprint, men's sprint)
BMX: -
Mountainbike: -
Diving: 1 medal
Equestrian: 6 medals (I hope that Germany will finally win a jumping gold medal)
Fencing: -
Field hockey: 2 medals
Football: 2 medals
Golf: -
Rhythmic gymnastics: -
Trampoline: -
Artistic gymnastics: 1-2 medals (Both on the women's side)
Handball: 1 medal
Judo: 3-4 medals (Germany had really good junior results in the last couple of years, i think there are 4-6 talents on the women's side that could turn out really strong + Wieczerzak and Vargas-Koch)
Modern pentathlon: -
Rowing: 4-5 medals (I hope that the tradition of Germany winning medals in both quadruple skulls events and men's eight will continue + i really expect a lot in men's single skulls)
Rugby: -
Sailing: -
Shooting: 4 medals (Of course the retirements of Junghänel and Engleder hurt, but Reitz and Karsch are still there. Reitz even seems to become a force in air pistol now ... Engleder got "replaced" by Beer + other athletes like Brodmeier, Link and Haaga should combine for another medal. I think the changes really helped Germany, in my opinion no medal chances were lost, but 2 new medal chances were created with the mixed air rifle/pistol team events)
Swimming: 1 medal (hopefully Germany will become stronger in open water swimming again, but sadly that doesn't seem very likely ...)
Synchronized swimming: -
Table tennis: 3 medals (I think the changes helped Germany, a new medal chance in the mixed team event)
Taekwondo: -
Tennis: 1-2 medals (Sadly the olympics won't be for another 2.5 years, right now Kerber and Görges would win 1-2 medals alone. Only a second top 15-20 player on the men's side is missing, Kuhn is on his way to become just that, sadly he doesn't compete for Germany anymore ...)
Triathlon: -
Volleyball: -
Beach volleyball: 1 medal
Water polo: -
Weightlifting: -
Wrestling: 2 medals
Total: 52-60 medals
The number seems really high, but i actually think it's not unrealistic. Germany has actually a lot of room for improvements in athletics (only 3 medals in 2016), canoeing slalom (no medal in 2016), cycling (only 2 medals in 2016) and judo (only 1 medal in 2016) + the new events in shooting and table tennis should help Germany. We also shouldn't forget that out of all the individual medallists from Rio only 4 reitred/will be too old to compete in Tokyo.
