It is the january GD letter 2014 i was referring to.
Quote: "We have now given all existing items (an astronomical number and a gigantic process) salvage tables, allowing them to be broken down into crafting materials. This was needed so everything which can be looted in-game has the potential to be made into needed pieces for the upcoming crafting recipes. Finishing this milestone was a huge data task and it moves us a big step closer to finishing the tradeskill revamp."
