So looking forward, what do we have left;
Slower updates. Fujino has clearly been struggling to get out the workhe wants to, and on time. Can't say why. Maybe he's having trouble balancing his work/life balance. He is also adding/experimenting with new systems, which can slow development time. And looking what he has left to do, there's no way to get it all done on time with just 4 monthly updates.
Suspected 4 updates remaining; but there's no way to fit in all the milestones left without making the next updates just a
flurry of important progression moments. And we know Fujino wants to bring the Administrator/Council plot forward next update too, and eventually that's going to need to come to some conclusion. I actually expect the update numbers will start shrinking as we get closer to 1.0, so that it's not actually 4 updates left. But then again, if he's going to take two months per update, maybe he can squeeze in all the content with only 4 updates. Feels like a sprint to the finish line though, when he could easily milk it for several more months of peak content.
In terms of the content milestones;
