They could at least write in the changelog that they work on it.
I agree, they could let us know exactly what they're working on, but I feel that some people are almost DEMANDING it.
We don't know what they're working on, but there are two cases, right?
1) They are working on it.
2) They are not working on it.
This game has made them substantial amounts of money. It's obviously a feature that they intended to be in the game, or they wouldn't have released with it. Do you honestly think they aren't devoting time and resources to keeping the golden goose alive?
I have no idea, they could very well be scrapping it, but to jump to that conclusion seems odd, and to be as hyperbolic as some are seems way over the top.
