On the topic of GENG vs. BLG (as I'm only up to there for now), I've tuned into CloudTemplar and Reapered's live stream/videos (here and here, respectively) on the quarterfinals and they believe GENG got a good draw (CT outright says it's the "honey" side, while Reapered doesn't say that outright, but that BLG has certainly faltered during swiss stage, considering their match ups and stats from those match ups).
So, it's an interesting take to think that GENG vs. BLG will be close. I don't think the fact that GENG got 3-0'd by BLG at MSI has as great an effect as people think (or at the very least, the people I listened to don't count it as much in their analysis/prediction). Just purely looking at each team's performance at the world's swiss stage, GENG is definitely heavily favored. But, once you start considering anything else more from history (BLG's dominant summer regular split, BLG 3-0 GENG at MSI, GENG's shakiness near the end of regular season), you'd shift a tiny bit towards BLG but not enough to make anyone predict BLG over GENG.
