Well, I have investigated a bit and there is no indications that Cuba and Dominican R. will not participate (there are articles about them announcing their teams). Their registration just doesn't seem to be ackowledged by the site for now... I guess.@Pabloffo Chile seems to just have picked other male categories.
Obviously I only care about Guzmán and Crismanich doing well, I don't see either of our women qualifying. Guzmán is the top ranked of the category but he has two dangerous opponents he could face before the final (Muñoz and Pie). Crismanich on the other hand doesn't seem to me like he has opponents anywhere near his level except for Lopez (which he shouldn't be facing before the final). But he just came back from a year long injury in February, so... regardless, I have a hope that if he misses quota he still can get the WC for -80kg as Brazil won't participate in that category.
