Doesn't even need to be that, I'm fairly certain they must have a 'Community Manager' (from my understanding most game studio's have someone in that role, even if it isn't in their job title), all it would need is for that person to pop in with a "Thanks for all the feedback guys, I know we haven't posted anything here or told you what changes we are looking into, but just to let you know we are taking your comments to heart" and I'm pretty certain people would be happier.
