You can expect it to be like the ilvl 70 crafted gear, some people will use it for a while, but it will be outpaced by dungeon/primal gear, also I think that with the increase in ilvl gear, we might start to see tier V material, so as with any game, there will be money to be made for a little while after the patch, spend you tombstones on the new crafting mats, either sell them, or craft the gear and sell it. Supposedly they will have new gathering nodes that require high gathering stats, but it's hard to tell how useful these mats will be, and how accessible they make these nodes, if they don't introduce new gear, then the materia might see a bit of bump up in price, but it will only be time before new gear is tossed out with much higher stats on it, so "nobody feels left out."
