I asked on the Discord if any movies are planned or in progress. According to what Fow has said, there is nothing planned or in progress. Apparently they want to focus on Subverse. I also heard that when/if they do return to movies, they want to expand Subverse lore. What I am interpreting that to mean is that in 1-2 years (optimistic guess), Studio FOW might return to making movies but they won't cover the themes their old movies did. So in 1 or 2 years, we might get a longer version of the Subverse game gallery clips.
I guess I understand, I imagine the movies bring in far less revenue than the game did. The movie genres were niche, and not monetizable on platforms like Patreon and Steam. I'd love to be wrong but I genuinely believe we'll never see content like their pre-Subverse works ever again, and I don't feel like waiting 2 years to find out.
