These main story updates and the tech update are probably like most big projects in real life. For those who have to live through them it's not that nice, but future players will be happy that it was and is done.
My biggest problem with the main story has always been that they didn't spread these updates. They had really good cliffhangers and no content to rework, so it would have been perfectly possible to release main story I -> Rhonda -> main story II -> Annie -> main story III -> Judith. I'm sure most people would have liked that a lot more.
As for the tech update? It's really just bad planning on the posing side, as it seems. I mean, it's not like we won't get something for the additoinal time it takes and sooner or later people will likely appreciate these scenes, new locations, added backgrounds etc. but right now but it's painful. Not that it matters really to those who don't pay, but I'm kinda impressed that DC's earnings still hold this well. Then again, the game is free and many patrons pay peanuts, so it kinda makes sense that they don't really care that much about a few $ more less.
And another question: after all, the DC promised to release a third psrt of the lewd scenes before the end of the technical update?
There hasn't been an official announcement, but it seems like we'll get another batch of scenes before the actual tech update. Ultimately it'll depend on how fast his team is able to complete the actual technical work. The more time they need, the bigger is the chance that we'll get even more content in between to fill the gap.
