They've been vague like this in recent FFXI updates which I only mention since it's now being led up by someone who was formerly from the ARR team so I figured to expect the same from ARR since similar methodologies and whatnot. Outside of SE MMOs I'm unaware of how open other developers are in regards to patch notes. I don't mind the vagueness though personally since they are at least communicating their intentions and probably don't want to over promise/under deliver should something occur.
