Well there has been one response now on the official forums from Sking regarding this and other high level issues.

He states that the developers are telling him they exist in game, even though they have not been dropped as of yet. Personally I think they are right, they do exist. But there is a difference betwen existing and implementing. We all know that Burning rock "exists",its simply turned off, or not implemented so to speak. I think that the green 60's fall into that same catagory. Maybe this is where the confusion is coming from.
