Destiny Factions

Ok, many of you who find out all leaked news the second it comes out already know, Destiny right now has 5 factions. FWC, Dead Orbit, Osyris, and two others one with a triangle symbol and one with a wing with a 7 in the middle. These factions are said to have different locations, so in my opinion, if you chose one faction, you be placed in a location (HQ) and that will be where you are centered around. Other factions will also be in the world where you can meet them and help each other with something, then split your separate ways. I'm guessing each faction also has its own special weapons, emblems, etc. and in those exclusive faction stuff, are also special unlockables like by doing special tasks or achievements. I don't know too much about what to expect from Destiny, but right now it looks AMAZING.
