Here's the thing... As an indie dev myself, i get it. DC really has no point (and as others pointed out, actually has no obligations) to release the tech update faster, even tho it's been almost 3 years going at it.
The money just keeps pouring in, their future is secured, they probably have plenty of other new projects idea they are working on. So people can bitch and moan all about it morning to evening if they want, doesn't change the fact that Summertime Saga is certainly a commercial (and arguably, marketing) success already and thus, lack any good motivation other than their reputation to release timely and sizable updates.
They can take their sweet ass time in planning, prototyping and exploring concepts for the future of Summertime Saga or whatever else they want to go to next. And let me tell you, that this kind of opportunity is fantastically rare in the world of video games in general, and he knows it.
Would i like for them to get along and finally release this damn update? Fuck yeah, i want to play this game one more time with the tech update so i can finally put an end to this whole saga (eh).
But also... DAMN, DUDE FOUND INFINITE MONEY GLITCH AND IS CASHING IT IN YEEEEEEWHOOOOOOOOOOOO!!
I'm half-joking but to be blunt; yes he is exploiting the shit out of it and i can't even blame him.
