Perhaps @
Marlamin can shed some light on this, but when you scroll through the icon list in-game, if you're trying to set an icon for your Warband bank tab for example, you see a bunch of interesting icons of unreleased items.
For example, the chain mail bikini teased a couple of years ago. But also a neat new shield and lance weapon. A dozen different armour pieces and weapons that look sort of like mail armour, for example the one with the chain mail coif that we saw a good while ago but never got in the game.
Is there a way to confirm anything about these items based on where they appear in the database? For example, the Wanderer and Vagabond sets we usually get in the Trading Post seem to be ordered someway in the icon list. Can we use this to infer when other unreleased items in the database will be in the Trading Post?
