There's going to be very little time between rounds (which is f*cked up given how long this round was) so it's not like the thread is overly premature...
Alliances I've heard are playing: Omen (in a smaller format), Ascendancy, CT, NewDawn, Angels, InSomnia, Vengeance, ToF, F-Crew, VGN.
That said, I've also heard rumours I'm starting up a new alliance.
