Conversely, I would actually argue (at least until they have something concrete to share) that radio silence might be the best course of action.
That way, there are no promises to keep, no hype to struggle to satisfy, and no deadlines to fall short of. They can work on development undisturbed, for however long it takes, to release a product that they are happy with. Lack of updates won't cause drama if there aren't expected to be any updates at all, so internal setbacks won't become public and damaging. In the meantime, they have the income from their side projects to keep things stable.
