DPC wrote in Q&A that he could make 100 or 10 statics per day depending on the difficulty of the scene. Statics can be previewed immediately and rendered in under four minutes.
Animations are much more complicated to pose. You cannot preview animations in DAZ (AFAIK). And if a animation has problems, you have to remake hundreds of renderings and you lost many hours or days, not four minutes.
Scripting dialogues is quite fast, the coding for free roams is complicated to plan but not to write. Mini games should be the same as EP10, according to his old announcement.
If animations were ready, he could shortly release the beta to his volunteers.
