I'm going with the two favorites(I think they're the favorites?) in Gen.G and TH.
Gen.G is making it in 99% of the time. Unless something crazy happens, I see them beating all three teams. (maybe not SEN, but Gen.G have been playing great and beat SEN in the normal B03 match.)
I have FPX winning round one but TH through the LB. FPX almost beat TH last time, and are going to be hungry to show they can play at the top level. But TH is better overall(imo) and I think they bounce back quickly. I think SEN isn't going to go down without a fight, but I just don't see them beating either TH or Gen.G in their current form.
Here's the rest of it for anyone interested:
