To further support these statements, Fujino mainly explains that the file size is getting too big. They talk about file size in relation to the length of events, and the amount of CGs they put. I don't know what feedback Fujino got in particular that prompted them to make this progress report, but I have a decent guess. My guess would be that people found the camping event not as exciting as they hoped it would be. Mainly because people wanted more Asuna CGs. But instead of talking about artistic or story driven reasons for a lack of Asuna CGs, Fujino focuses more on the file size.I sincerely hope you are right about part 3
It also doesn't seem like Fujino is doing any dramatic shifts in production, but like Queen said, it's Fujino starting to admit, or maybe recognize they need a Part 3.
