I have no idea what SOTS means, but if you mean how many more updates I think 35 might actually be close. If they don't let things slide, then 32 is the number I come up with, and the game will be essentially complete and release quality by 2022. They need to run both PTU and PU all the time though, so they don't push a broken patch.
What I want to know is how many of these CIG is breaking: (My 5 quality lessons to a software development team last year. They avoided a black swan by the skin of their teeth) They are breaking #3. I think several others.
- "It compiles" is not a synonym for it works
- If the requirements don't make sense to the developers, the software won't make sense to the users
- Never patch in production, without patching and testing in your test environment first. You're not that good.
- You can test it now, during development, or you can test it after a user discovers the bugs. Your choice.
- Just because something is cool to do, doesn't mean it should be done. Follow the requirements, and only the requirements.
