Being a software developer myself, I just thought I'd add my input:
People have reason to complain about the length of the current development cycle, it's too long. I know, content takes time to produce, but projects with development cycles this long tend to start failing. Why? Because the developers are trying to add too much content into each release. They'll eventually be unable to maintain the code and bugs will start to go unfixed. After that, things will just get even worse.
Fixing the problem would be rough for a few months, but really should be done.
The first thing they need to do is adopt an Agile methodology and then start releasing content every 2-3 months. Of course the save compatibility issue would need to be resolved in the first release so that people wouldn't need to start a new game every time.
The project is too large for Dogeek to be coding by himself. There needs to be at least two developers so that they can pair program and review each other's code. This would increase productivity and greatly reduce the number of bugs being introduced into the code.
Which leads us to the posing/animation issue. The fact is, if it's such a bottleneck then DC shouldn't be working on content for the next update, he should be helping with the posing and animation. If something in the development cycle isn't working, fix it!
All that said, from where this game started to where they are now, they've come a long way. Has everything been perfect? Of course not. Is it easy to complain about that? Of course. Does that actually fix anything? Not really.
The best thing you can do is: offer suggestions (like those I've made above). If they don't want to make the changes you think they need to make, then you don't have to support them. If you're not supporting them and still complaining...then you're complaining just to complain and it's not going to change anything.
** Note **
I know someone is going to ask, so I'll say it right now:
Don't ask me how long it'll take me to update the incest patch when 0.18 drops. My current patch only replaces lines, which is okay, but not really great. The game has multiple characters that say the exact same line. This means that replacing the line for one person changes it for everyone that says it. The new patch will take longer to release because I'll be doing it properly this time.
