Canada's WAG team just got announced, Rose Woo didn't make it but Ava Stewart did. Stewart is a first-year Senior. There's also Ana Padurariu who just got too injured over the past year, dashing her hopes of Tokyo before starting her NCAA career with UCLA in the fall.
Then there's team Spain, Cintia Rodriguez and Ana Pérez, who was part of the team that helped Spain earn a team berth to the Olympics, both out this year due to injuries.
Becky Downie and Ellie Downie most likely making team GB had it not been delayed and not having to deal with the death of their brother leading up to Olympic trials.
Gave both Larisa Iordache and Rebeca Andrade a chance to earn themselves a nominative berth to the Olympics.
On the MAG side of things, Artur Dalaloyan tore his ACL right before Euros this year and is unlikely to be back at full-difficulty (the level Russia needs him to be) for Russia to realistically challenge for the Olympic team gold against Japan and China (who look really damn good).
Oleg Verniaiev has his FIG license suspended earlier this year (still suspended), slashing Ukraine's hopes for a team medal with a very promising Junior who turned Senior this year, Illia Kovtun.
Turkey earning their 4th nominative Olympic berth (basically enough to form a team) at Euros this year with Adem Asil switching from representing Egypt to representing Turkey starting in March 2020.
The list of "what ifs" literally go on forever... it's such damaging year for some individuals and programmes, but presents hope in others.
