I believe it was said, though I could be wrong, that the creator was surprised how well it was received and didn't plan on making anything past the chapter that introduces the Dark Elf. But seeing it was received so well seemed to have re-sparked their interest in making it.
It's likely we'll see at least one update this year, if you want my opinion on it.
The Elder Scrolls canon states that the Orsimer were created when an Aldmer(common ancestor to High and Wood elves) prince was corrupted by Malacath and Boethia iirc.
I've never really liked how just about every fantasy story/movie/game ect. always depicts orcs as stupid, dull, rapy, murders because "they just are." It's refreshing to see one of my favorite fantasy races put in a different light
