We're all waiting for someone to come up with a good practical use for Karma I guess. The blockchain is there, someone needs to put it to good use and that doesn't have to be a dev.
There's not much the devs can do at the moment. Adding new features to an old coin is not worth the effort, those are mostly just fads for a quick pump and dump anyway. What value would Karma gain by adding anon? None.
The original ideas behind bringing Karma to emerging markets and trying to give Karma a purpose as a reward system for good deeds are still great. Its just that nobody is apparently up to the task of tackling these.
So I guess nothing will happen until crypto (Bitcoin or other coin) will be mass adopted.
