The Gc2016 demo was the first video that made me feel like the 250€ i spent in 2012(?) are maybe not a bad investment after all
Still the game has a looong way to go before it can be released, maybe beta by the end of 2017? Release 2018?
Even I'm not sure anymore so I give up predicting the release date.
Tony who is in charge of the Persistent Universe, when asked in his last interview, stated that you need a solid foundation for the end game features you hope to have and that's the game development philosophy he pushed with Chris. The more time you spend building the foundation now the more time you can sit back later and basically just make bank because you did all of the heavy lifting from the start. That's basically what their current development plan is. Like it or hate it that's what they are doing.
So we are seeing this play out in 3.0. Major changes to the foundation but not a major content push in terms of seeing multiple star systems or tons and tons of missions. Just the basics many of which have been in development or a complete revamp for the past 12 months.
With so many major basic features still missing it's obvious the game is not coming out in 2016. I expect to hear that SQ42 is delayed until next year.
If you want to predict the release date it may make more sense to track the game based on the foundation of the game. Until that foundation is built you will not see CIG spend massive resources building 100 star systems.
With that in mind they are about 2/3 of the way there once 3.0 launches. Things like the intelligent mission system which has it's first pass in 3.0 is a good indication of development progress. As you see that feature fully mature you will get a sense of how long it will take them to craft the thousands of missions people will expect to exist at launch. Like procedural planets, space stations, landing zones it's a tool designed to rapidly build content with existing assets.
If they stick to their design philosophy at some point they will reach a nexus where all game features/tools are done and all they have to do is feed it more assets and spend a significantly less time working on features.
I'll let you know when I feel they reach that nexus but I feel most people will see it themselves without any help as star systems, missions and basically just content suddenly floods the game rapidly and many will be shocked. However that will be because they pulled off their game design philosophy and reached their final milestone.
