Nah you cant be more wrong i would say... first of all, DPC already made it more than clear that he doesnt plan to drag out the game (and he did it more than once already, so i guess its fair to believe him), he is aiming for 16 total episodes, maybe +1 for doing epilogues or such (the intelrude is not included in those 16 episode count)...
second, so far the longest wait for an update were 9 months, and with every update he added more and more renders and animations, which is the reason for increasing the development time and ep10 will be another peak regarding the numbers... of course, iam one of the guys around here who thinks that its not necessary, but in regard of content and such DPC is just crushing every other DEV around here, nobody can deliver as many content as DPC does in the same time, especially not on that high level of over all quality. Most episodes of being a dik have more playtime than most COMPLETE games around here. Dont know why anybody can think that this development is the kind of a "milker" thats just absurd.
DPC has just this one fault... he is going overboard with to much unnecessary stuff. But he is not doing this to drag out the project or to milk it, no he just cant stop himself cause he LIKES creating all that stuff. Thats all.
