Glad you're interested in Anni's stories!Also, hope we get to visit Jassira at some point cause when I heard Annika describe it, I wanna go there now. They got Catfolks, Anubians, Tiger beastmen, Snake people, Ant-like people, another type of Harpies and more. Sounds like a fun and exotic place to visit. But I feel going to places like Jassira, Kitsuhon and old Belhar are VERY VEEEERY big content to add so there's a chance the dev might not add it in the future or even if they did, it would only be a small part of their country you can explore.
Sadly, like Wolfram, I have to say that no, y'all won't be going to Jassira in CoC2. Maybe in a future game.
Also, note: many of those things are from the places beyond Jassira, on the other side of the great sand sea. Ariana and Xenaspa are the countries that have those tigerfolk, nagas, myrmarcs, harpies, etc. Some of them also show up in other places! For example, there are also myrmarcs in the far south of Belhar, tigerfolk in Macah, and so on.
And don't forget that there's also an allusion to crocodile-folk living in Jassira, too~
