Ocean's said in recent devlogs that is the plan after chapter 1, at least size wise We'll see what happens after the two games get over their next updates. I think the reason for this being larger is he wanted to start all (or at least a significant number) of the LI paths in meaningful ways, which requires a lot of content.If however, he decided to do one mammoth 6000 render update every year and it meant half the number of chapters, it's still the same daily render count.
Judging an update by the number of renders right now is the only metric we have, but once we have the update we can see whether it's satisfying as a game. A lot of games with faster/shorter dev cycles have left me to wait until there was sufficent content to play a couple of updates.
It's not as if our thoughts will change the dev cycle, more important is changing Ocean's mind on Ayua's and Maja's LI status
