I remember, a couple years ago, when Final Fantasy XIII was released after years of development hell, that someone "leaked" that the dev team was around 180 artists and 20 programmers. No wonder why FFXIII was a beautiful audiovisual experience, but a game you "watched" instead of a game you "played".
Looking at this game's "dev diaries" at a whole I've noticed a trend. Everyone's an artist. New sounds/SFX, new lighting, lip syncing, new waifu models, cool explosions, but... who's ACTUALLY MAKING the game? If they've lost more than half of their staff, how many programmers do they have left? I can only identify one, HungryJJ, and he/she is new to the team.
And the sad thing is, they could just add scenes to the Pandora system (after all the sex scenes are completely separated from the "gameplay") and delay the game updates until they get someone to make them. After all, the "core" StudioFOW expertise was in making porn movies for years, right?
right?...
...unless the people who left are the "core" StudioFOW artists.
Only time will tell.
PS: The DD18 said "Please check out our new features overview video for an indepth look at what’s coming up in Subverse’s next major content patch in November!" The new DD19 says "we are setting the release date of the Fortune chapter to December 19". Those are quotes from their own website. Don't keep your hopes up, there is no more confirmation that the update will be this year than the last time.
