I gotta think that yes, there will be depreciation. I've already sensed stagnation in the market and lack of interest in chaos axes. I think that even crystallines will be of little interest immediately after the release of factions. However, once the breadth of items, and the frequency of drops is established (a few weeks to months after Factions release), I think Prophecies items will have value again. I don't think that they will be worth as much as now, or in the past, but I think the rare prophecies items will indeed hold at least some value in Factions. I mean, keep in mind that there will be newcomers to the game who will never have had a chaos axe before.... who knows, maybe even firey dragon swords will make a comeback
