It's a logical addition -- for women who wear them, the hijab is a big part of their visual identity, and Unicode's been working to make it so all people see themselves in the various options they offer. In addition to the face wearing a headscarf, there will also be two options showing the scarf as a loose item of clothing as well as in a "ghost" form where there isn't a face visible.

There's no word on when Unicode 10.0 will be released, but there are plenty of new emoji coming in the 9.0 release which is expected to arrive soon. Among those are a shruggie guy, facepalm and selfie emoji. One might argue the hijab should have been added before these, but at least it's coming eventually. As for what else may arrive with 10.0, we can look forward to a flying saucer, a pretzel, some dinosaurs and a zombie, among many others.
