Unlocked (quest reward) Chests

Hi.

I was wondering if anyone knew of a place with information on these special chests. I have looked at Guildwiki and its information is quite limited. I ask because I was questing in FoW when someone told me that if you do not open the chest but wait (he did not say for what), you will get a better item later. I pondered the idea and decided to search for any info and that brings me here.

The FoW chest rumor is false. They'll only drop purples and don't get better when you wait.

Unlocked chests are:
Hidden stashes in Pre-Searing - white crap items
Chests in "The Deserters" quest - don't remember what they have
Chests in Kilroy Stonekins quest - purple items
Chests in UW/FoW - purple items
Chests in HoH - gold items

LOL, that silly rumor is posted here every other day.
