To be fair, it seems like this time they massively underestimated the time it would take to repose the game. The art required for the new update is indeed finished for 2-3 months and the remaining art tasks are mainly exporting stuff, which is something DC wants to do himself and which, as it seems to me, will be done when they are needed.
In the last months DC actually hired 3 more people to help with posing, which is something he probably should have done before they started with the tech update.
Then again, it's not like all of this hasn't hurt his numbers. Back in 2018 he managed to grow his earnings by ~35.000 $ a month from january to december and by another ~20.000 $ in 2019, while this year he only added ~7.000 $ (depending on when and how one wants to count) which is pretty close to stagnation.
Of course that's still an insane amount of money, but one has to consider that SS is probably among the most played games in this whole genre globally and actually very popular on mobile, too. He's literally got millions of downloads per update and if DC had cared a bit more during those last 2 years he'd very likely make a very, very comfortable 6 figure number per month by now.
