Huh, I'm afraid of jinxing it, but I'll give us the vote.
In reality there are so many good teams out there. I'm sure CC will get their best team back in action - and they're a mean killing machine.
RL is in form, Slayer exceptionally so.
Tenacity 3 has an incredible 3v3 team as well.
And then lets not forget that every1 of these tournaments so far has been able to produce some pretty big surprises.

Oh and, if VS will start training, well they could just pwn us all.

That being said, the same holds true for GpW.
Ought to be fun
