If you consider ch5 disappointing, there's not really much point extrapolating from numbers for you is there? I mean, a lot of people enjoyed Ch5. I'm not going to argue about the rework, because that's been done to death, and everyone's made their own mind up about it. Suggesting it wasn't work that took time is just a way to say, "why isn't Ocean creating the content I want, sooner?" You're effectively saying that only the content you want to see matters. Well, S2 Ch1 is supposed to have content for all the LI's, even the ones you're not on the path for. Either you like the game and it's potential enough to wait for the update or ....you don't.
Pretending that nothing happened in development is just ridiculous. Ocean dis spend 2024 doing things. That's when the rework was completed. Again, whether or not you like the rework, Ocean did it, that is actual dev time.
Regarding WiaB, well, the WiaB log is interesting. We'll see how soon Ocean renders that last scene, seeing he's anticipating being on postwork by the next devlog: 1 scene and animations left. But since he's gotten the work station he's been able to do animations while setting up other scenes. Also, old Wiab was around ~4500 renders before Ocean restarted. So Ch4 nearly has the same amount of renders as the whole original game. I can see the value in the rework of that.
Both of these updates will be the biggest updates Ocean has done in any of his work. If you can't wait to see if there's any content you'll stick around for that's completely up to you.
