Developement stopping has nothing to do with the new open source camera. It has everything to do with the fact that at the moment there isn't anyone with enough skill, interest, and free time that is willing to contribute to the project. That's not to say that is permanent, someone could come along (or return) at any moment. Please feel free to step up yourself, that is the point of this community after all.
There's just no way to know how and when development will happen and there's no point in speculation.
