Emphasis: This is a prediction, no spoilers were used in the making of this blog post.
I predict Sarah sides with the brains, in order to blindside Tony.
I say this because she no longer trusts him, and they will take him out in order to appease her. This makes sense of his edit. He's a large player and the merge boot is often a very large player in the game.
LJ finds the Tyler Perry idol. Thus, he's the last one remaining from his side. He is kicked out when they split the votes against him, flushing his idol, thus sending him home the next week. He will play his idol in two weeks because he thinks they are voting for him, but they will vote for someone else (not sure about that one)

But Matt or Corinne (I forget who the merge boot was in Caramoan) weren't huge at all.
