Kharitonov VS A. Emelianenko is gonna be great.
Usually Kharitonov can handle any one, any size - but Emelianenko isn't your usual giant, he's got crazy hands and loves to stand and trade.
I don't think you can compare Kharitonov to Vovchanchyn though, Vovchancyn was more of a heavy-hands type of guy. Sergei is more technical, it's like he sees his opponent as target practice. And Sergei is always moving forward, always walking towards his opponent. Igor has little or no ground game, Sergei is great on the ground (Sambo).
I think Sergei can evade Emelianenko's attacks though, like CroCop, wait for him to gas a bit, and then work his magic. Still though, I'd say it's 51/49 in favor of Kharitonov, it could go either way.
My pick for the OWGP: Mirko - if he can work on his stamina and survive Wanderlei without injuries.
If not, I'd go with Nogueira, whom I love, but I don't wanna see him get beaten by Fedor for the 3rd or 4th time.
