Wait, he's releasing this in events not full sessions? So that would mean that the morning session will take the same amount of time to make as the previous full day? That would mean that it will take him 3 years just to complete this day. ffs, I was told he was going to speed his production up, not extend it
It seems you've missed out on quite alot of information. In previous updates, L&P released 1/3rd of a playable day, so 3 updates for the entire PD12. Now, starting with PD13, L&P decided to go with more frequent event-based releases, split into 10 updates for the entire day.
He started working on update 1 this Monday, and so far we're seeing 5% progress each day, alternating between 'Created Scenes' and 'Rendered Scenes'. We're currently looking at approximately 40 days to complete both CS and RS if he keeps up this pace. After that comes the 'Photoshop' and 'Programming&Translation' part, which in theory shouldn't take much longer than 10 days combined considering the render count is most likely way lower for 1/10th of a full playable day, unless he decided to increase it once again.
That's 50 days in total for update 1 out of 10, not counting in any possible breaks and holidays etc. This is just my personal estimate, and I highly recommend following
Talcum Powder's graphs as they are probably way more accurate.
Anyway, since we're in a really early stage of the development for PD13, we have no way of telling if every one of these updates has roughly the same size, or if there are smaller/bigger ones inbetween, so the total amount of time required for PD13 to be completed is pretty much unknown at this point. But if you were to ask me for my personal opinion, I'd tell you that we're probably looking at 18+ months of development for PD13.
