I think Marquardt is going to keep the fight on his feet, because he does have very good striking and is confident enough in his striking ability. This is going to be a very good fight, style-wise Marquardt is all wrong for Silva, but it is going to be interesting when they are on their feet. I can't really pick a fighter right now to win, despite me being a huge Anderson Silva fan. I will say this though, if Silva beats Marquardt, I don't think there is a MW in the UFC that would be able to defeat him.
I think Yushin Okami has a pretty good shot. I'd at least like to see a rematch. He should probably fight Rich Franklin first though.
