I don't think anyone is actually leaking info. I understand the theory of a smokescreen and what it would hope to accomplish. But no GM in their right mind is going to believe any of the supposed leaks they hear in the media. They (meaning all the GMs) know that none of their colleagues are going to believe any of it either, which makes the entire smokescreen process pointless.
In my opinion (and obviously that's all it is), there is no smokescreen. There is simply no point to it.
