Guild Wars 2

Does anyone know if the emissaries that were in the crowd pavilion is still somewhere in the game. I wanted to get some recipes/skins from them, since I still have a LOT of those sprockets lying around. I found that the zhaitaffy merchant from dragonbash is now in LA, so was wondering if it is the same for the crowd pavilion ones. If they are gone: Are they coming back at some stage?

Yes I would like to know that too. Have casillion sprockets in my inventory and afraid to delete them :]
