The ball sucking is the reworked version. Initial release had Vi sucking his dick, which CG thought was going a bit too far too quick, so he toned it down a notch. He's said it in the devblog that was posted above - he's not releasing until it's ready as the Ch06 rework was bad enough. He's not doing it to keep any "crowd" happy, he said as much before.
But I must admit the delays are getting more frequent lately. A delay is in itself not an issue but he might have to overthink his release dates and perhaps try to improve on his project management seeing how his plans don't seem to work out. He's already cut the next Chapter in half to prevent prolonged development cycles, and yet here we are looking at another delay. I wanna say it's the holidays, but I got a feeling he's once again bit off more than he could chew in the time he gave himself, or maybe he's once again trying to go bigger with the next Chapter which I think will eventually backfire.
Edit: To clarify, I'm not trying to say what he has to do or not, but my opinion on Chapters is simply that there is a point at which you run into diminishing returns territory. Releasing increasingly larger Chapters will eventually cause the story to come to a crawl in a sense that he'll only be able to release 2ish Chapters per year, atleast when looking at the current projectory. And while those Chapters would no doubt be well fleshed out with lots of detail and interactions, it would also cause the world of MNGF to slow down as every scene ends up with substantially more images - which leads to fewer scenes, less story progress and releases in general. Said it before, but I think it's important to find a good balance between quantity and quality. I really hope he's not trying to make every Chapter larger than the one prior. Anyway... Fingers crossed!
