I suspect people will probably adopt it if they like it mostly for new projects.
We still do have a lot of modules to write yet, so if you are interested in that, stop by talk.msphere.io - I'm open to a lot of enhancements there, but also want to keep it somewhat controlled.
A lot of the early adoption is no doubt going to be folks doing CM-based builds for images (EC2, docker, whatever), where everything remains pretty disconnected.
A mid-way adoption stage might be using opsmop to run existing ansible content, though ... that's really pointing towards wanting to add something like rsync, which is easy, but... I need to think about that a little bit.
