Now that qualification through the World Championships is finished, the next events that offer Olympic quotas are continental championships and the World Cup series. Depending on the results of these events, gymnasts who are waiting for a reallocation spot to qualify through the World Championships might have a chance. I'll try to list the possibilities.
Men's artistic gymnastics:
I believe that if we have any changes at all, it could only be Marios Georgiou qualifying through the European Championships, what would allow Jessen David to qualify through the World Championships; or maybe, though veeery unlikely, Andrey Likhovitskiy qualifying in an apparatus through the World Cup series, what would allow Tomas Gonzalez to qualify. However, Gonzalez has a decent chance of qualifying through the continental championships, so Andrei Muntean would be next in line.
Women's artistic gymnastics:
On the women's side, there's just a very small chance of Chusovitina competing at the World Cup series and qualifying through vault, but right now she's not even in a top 10 position. She is known to participate in many World Cup events, though, so she might try to qualify through the World Cup series despite already securing an Olympic quota through the World Championships. Either way, if she decides to do this, Ryan Megan would be able to qualify. Extremely unlikely to happen, though.
I honestly don't think any of these things will happen, though.
