I found a Fighters Guild in TESO and now I wonder whether or not some other guilds are in the game. As far as I know there are 4 guilds that are always present in Elder Scrolls games (Fighter, Mage, Thief, Assassin).
I'm really interested in the Dark Brotherhood since I play a rogue but it would also be nice to know where the other guilds are.

Right now there are three NPC guilds in the game, which you can join - all offering a unique skill line for your character:
Unfortunately, some guilds didn't make it right into launch , but they're scheduled to be added at a later date, most likely later this year:
Also, there are quite a few other groups in the game. Some you'll be able to join, but they won't necessarily grant you direct bonuses or skills. Warning: spoiler ahead!
