The problem is that even if they reveal information during fan fest, most of the content promised or hyped up are not implemented or it takes them a whole year/two before even considering of putting it into the game. In most cases we see a watered down version of something that sounded very promising and exiting, looking at you PoTD. Or content that was exciting than needed to be nerfed 2 months later (raid content for example). After all, I can see why you think that the game gone stale and consider of moving on, but I think there's no reason to wait till the fan fest live letter announcement etc. If yer done, yer done, move on.
