As of today I think the United States will win 3-2. But I need to find out the health of the players right before the final so I can make a final prediction then.
I don't think a Russian doubles team of Youzhny and Tursunov will beat the Bryan Brothers in the vital doubles point. But I think a team of Youznhy and Safin could if Safin is healthy. Safin's health is important to Russia for the final. Even if Marat only plays the doubles if Russia wins that point they would win the Tie and Davis Cup final by splitting the singles matches. It might be asking alot of Marat at this point of his career, but Russia needs him healthy and in good form for the finals.
