A few of these i'm going to do a synopsis for. Not to sway anybody's decisions, just simply because i am a nerd.
Kane and Mankind are still fresh, so i think their stamina is too high in comparison to the others to really get thrown out at this point by anybody(even though everybody in the ring is a titan)
Hogan hasnt been too active as he has not eliminated anyone yet, and i can't see John Cena coming in and going after him first. Cena isn't enough of a heel. He's the ultimate good guy, and a Characteristic of the good guy's is to go after the biggest threats first. Head-strong Naruto style.
Undertaker has eliminated 2 fighters so far, and has been in the battle since the beginning. Combining his probable fatigue with Cena's go-getter attitude, I pick Cena to eliminate the Undertaker this round, with the help of a vengeful-sock wielding Mankind. It's a ballsy pick that will most likely lead to more wrestlers in the ring next round, but i'm assuming the rounds with odd amounts of fighters are more likely to induce a throw out than the even rounds, due to 2 on 1 tag-teaming.
Here's how i see the dynamics in the ring this round. -
Kane goes after Hulk Hogan after throwing out an outclassed Edge.
Mankind attacks Undertaker in classic grudge match style, and Cena runs in and helps Mankind.
