I don't know enough about AE to comment about Infiltration so I'll just say vulva.
AE wise? I still like PR Balrog because he is more or less notes proof. Because of this, he also has a good chance of running the Japanese gauntlet.
Xian is obviously in good form but will probably hit people who know the match-up well. Even then, it isn't long sets so he might still do some damage.
Sako obviously could do a lot of damage if he actually shows up. It remains to be seen if this is going to happen or not and is one of the more hype things about the tournament to me. If he makes it to top 8? Look out.
Fuudo is still very strong and seems the least likely of names like Daigo to be knocked out randomly. You wouldn't back him to beat Infiltration though because that is where his consistency works against him. Daigo could do anything, but he seems pretty susceptible to characters like Cammy or Ibuki. Unless he has an alt he is comfortable with, I think his Ryu will end up to be a sinking ship.
The wildcards for me are Ryan Hart and Bonchan. In theory they have bad Sagat match-ups to deal with, but I also think they are the players best equipped to "know" those match ups well enough to overcome them anyway. As per my predictions, I wouldn't be surprised to see players like these two in top 8 along with some relative unknowns as the big names get randomed by match-ups themselves or knock each other out.
