Do you know if they are going to have guilds in this game like the last elder scrolls? I also saw some people wondering if there are going to be vampires or werewolves I hope they will have both. I was reading about it in game informer and it looks unreal I cannot wait for this gam

I don't think there has been any confirmation about this yet

Maybe there's some info from the game informer article but so far I haven't heard anything confirming guilds

Guilds have not yet been confirmed, but we can only assume they will be included based on previous games. For all the information we currently have at our disposal, check http://www.gameinformer.com/p/esv.aspx.

while there hasnt been any word on it, im sure guilds will be in, i mean, why would they exclude them?

guilds provide a majority of the quests in the games, so it'd be stupid leaving them out.
