So from the leaked screenshots of June's Game Informer we know that as players we'll be able to join the known guilds of the world (Thieve's Guild, Fighters Guild, etc.) Have we heard anything at all yet about there being player guilds/clans in game yet? I'm quite curious if this is going to be a feature we see or if the community wants to see.

It would be great if players could form sub-groups underneath the main guilds and reap some sort of benefit within that said sub-group.

For instance being able to train other players in that group.

Personally, I hope the Fighters' Guild, Mages' Guild, etc. won't be in. On roleplaying servers, people'd likely set up the 'unofficial' Fighters' Guild (which would be roleplayed as the official one).
