You only evet had visibility into a daydream that changed. What good is, no scratch that, there is no good in knowing something that you only think you know. It's negative value. It's worse than knowing nothing at all. It doesn't matter how much you want to know, and how good it feels to have that want pacified.
Similarly, this is also why even if someone does publish a road map, you should ignore it and only deal with whatever exists as it exists right now. Make all decisions, including looking ahead, based on nothing but the current state.
