I'm probably white knighting as usual

But I'd tend to think that the wording about the feature rework was very poor. I find it hard to believe that they haven't started on it, that they don't know what it's going to be, and that they'll start thinking about it at the end of year. What I know for sure is a whopper is that they will let us know what it's going to be when they start to work on it, they never tell us anything like that until it's about to appear in the game, or it's been released..
Most likely they've decided what it's going to be, and they've started developing the code, but for some reason they've ran out of time to include it in update 15. I think it's likely that they have reduced the development team, and this is the reason it's not in update 15, but of course it could also be that they underestimated the amount of work, or they ran into issues with the existing code base that make it take longer.
