Okay let's do some math!
This week DPC added 238 renders and 8 animations, significantly up from 144 renders and 5 animations last week (and 132 renders and 9 animations the week before). That gives us a September average of ~171 renders and 7.3 animations per week.
There are 275-425 static renders and 47-52 animations still to process. That translates to about 2-3 weeks to finish the static renders, but about 7 weeks to finish the animations. DPC has had a full animation queue for some time now, so I think the only way the animations take less time is if the remaining animations are disproportionately shorter than average. That is possible, but I suspect DPC sorts his posing by scene or by inspiration rather than length/complexity.
If we get slightly optimistic, I think we're looking at 6 weeks to finish the animations. That should leave plenty of time for DPC to finish the remaining renders and any other tasks (posing, writing, coding, etc). After that it's just down to testing and proofreading. Some of that might be done in parallel with the last few animations, but I doubt DPC would want less than a week to poke around with the final product.
So I'd say the earliest we're getting Episode 6 is November 13. That's neither auspicious nor soon, but it could be worse.
Looking at it this way, however, I have to admit I'm skeptical the animations are worth the time. I've rarely felt animations add much to adult novels compared to good static renders, and BaDIK's animations are no exception. DPC mentioned some new animation techniques so maybe Episode 6 will change that. But otherwise, I hope DPC will cut back on animations going forward rather than continue to escalate the numbers.
