(Okay, gonna try to make this the last post in this vein I'm making here for a good long time. Let's discuss context. It's good, probably.)
A disclaimer wouldn't hurt, but ultimately I feel like the solution to the stuff you're describing is proper communication. Not just an out of the left field statement, I don't think that'd quite work for people, but a stream of consistent updates. I think most patrons are quite understanding of such changes as long as they're aware of what's going on behind the scenes, they're passionate enough to support EZA directly after all.
Not quite the same thing as what you're describing but related is the Game Sleuth discussion this thread had not too long ago. The current information release too, really. I do feel like EZA has been doing a somewhat poor job of keeping their closest fans, the patrons, informed in a timely manner. Initially it seemed like Cup of Jones was going to serve this purpose, but it isn't quite suited for this anymore with its current release schedule.
