Yeah, I had a bit of a look and a good number of the "not implemented/ignored/delayed" is hardly surprising. The game is still in development and the stuff in "broken promises" is basically slipped ship dates, hardly a massive shock.
Given that they seem to be tracking basically everything, even down to the level of "mentioned once in an interview that this might sometime be possible", I would be super interested to see this after an official 1.0 release and for the years of patches after.
I really hope they have history tracking for the entries, so you can see how they have been categorized over time and when they went from one status to another. I'd be way more interested in those stats, seeing what they have delivered over time.
However I'm sure this will stop being updated once CIG start releasing stuff as it appears the only thing keeping it going is anger.
