I'm interested in all of the spiritual successors, but it should be noted that the standout quality of DE to me was always the writing and the world building, and I don't think any of the prominent writers are involved in this project. If I remember right from the announcement some months back this project has a writer from Destiny 2 and Suicide Squad: Kill The Justice League, with the main Disco Elysium connection being Piotr who was systems designer for ZA/UM.
It still sounds interesting from the article and I'll check it out when it drops, but it isn't really the spiritual successor I personally am looking for. That would be something by either Red Info (Kurvitz/Luiga/Hindpere/Rostov) or Summer Eternal (Argo Tuulik et al).
