Well I think Kawajiri, JZ/AOKI winner, and Ishida are all going through pretty easily.
I see Kawajiri vs Buscape as a repeat of Kawajiri vs Azeredo.
I think JZ will handle Aoki and than destroy Nagata (Why is he still fighting?)
And Ishida shouldn't have to much trouble with Uno in his first fight back after Dida broke his face literally.
Now Alvarez vs Hellboy should be intersting. I'm going to go with Alvarez because I was a fan of his until he broke my heart by kicking Dida's ass and while I love Hellboy, Alvarez is bigger and a better striker.
