Some players (Like bals mentioned above) will now loot things in old content, and may sell them on the AH, that may cause a small drop, but nothing outside of the ordinary that occurs now, and would probably be temporary (think like this situation, which occurs now: a few players notice old mats are selling for 100g a stack, these players farm said mats, stockpiling them, suddenly, there's a massive quantity of this said mat on the AH for <1g a stack, after things settle for a week or two, prices climb again because these players aren't farming that mat again. I think the comparison would be similar.)
And the third type, who will now use AoE looting, but likely just vendor it all out of habit/laziness, having no effect.
All in all, I think it'll have little effect on the AH prices, unless some rumors are spread causing a HUGE amount of players to farm a specific mat (an example of this on my own server was a period of time where players were selling Dust of Disappearance from the vendor for almost twice its worth, since there were apparently people who thought it was inscription only, after figuring this little niche market out, people butchered it, to the point that it was (and some days still is) cheaper to buy it off the AH than the vendor.) Point being, unless some unique "niche market" opens to old cloth/enchanting mats and goes viral (at least on a server level), nothing is going to tank due to AoE looting.
