Well, Zantai might do a few more balance patches, if the community points him to outliers, but probably smaller ones and less frequently.
Should feedback of Xbox players result in some quality-of-life features, these might be added to the PC version, too.
Maybe they will add bonus content (to FG). Could happen if artists and designers have an unexpected downtime…
Severe (your milage may vary) bugs will be sorted out. But I expect them to focus on their other projects.
