This is the response to a private message to Tidbitz (new CM) about whether or not Defiance OG is going to be supported or not.

"This has been brought to my attention already indeed. Unfortunately i do not have that info yet. Once I learn more about this topic I'll inform the community."

So I guess for now it's just a waiting game, I do hope that they don't just drop it altogether and that they do continue and update it.
