Who do you want to win the majors next year?

I've been thinking about this recently and I've been trying to figure out what would be the most interesting match ups for the finals of the grand slams, next year. Obviously the Nadal and Federer matches, would probably first come to mind but I tried to pick other top players who would not only be likely to make the finals but would also be capable of playing a great match.
Well, this is what I've come up with for now, let me know what you think:

Australian Open: Nadal vs Del Potro

Reason: Del Potro killed Nadal in all 3 of their meetings on the fast hard courts this year, but the Australian Open surface is different. It's slower than most hard courts and produces a higher bouncing ball, making it a much easier surface to play on for topspinners. Even though Del Potro still has a height advantage, the slowness of the court combined with the higher bounce would give Nadal a fair chance. In fact this would probably be the most neutral surface that I can think of for these two players to meet on. Neither one would have an overwhelming advantage and it would all come down to who played the better match.

French Open: Nadal vs Djokovic

Reason: Since there's already been 3 Federer/Nadal French Open finals, I decided to make my French Open choice between Nadal and Djokovic. Even though Djokovic, has never beaten Nadal on clay, he's come very close several times. Djoker, frequently takes sets off Nadal and he's even had match points in their meeting in Rome 2008 and then earlier this year in Madrid. I'm not sure if Djokovic, would really do any better against Nadal than Federer would but I would rather see him get a chance to prove himself in the French Open finals. Even if Djokovic, loses in straight sets, I know he would at least put up a good fight.

Wimbledon: Nadal vs Federer

Reason: There's just no question that the Federer Nadal matches at Wimby are classics. I don't know anyone who wouldn't want to see more of them. Regardless of who wins, you know your going to have a great match and that's why I'm picking this for the Wimbledon finals.

US Open: Del Potro vs Tsonga

Reason: This one was a bit tricky for me, but I eventually decided to go with Del Potro to make the finals next year, because I'd like to see him try to defend his title, on the biggest stage of all. As for his opponent, I wanted someone who he hasn't played a bunch of times. That's why I'm going with Tsonga. Ever since making the finals at the Australian Open, Tsonga, hasn't come close to winning a major, but I think that would probably change, if makes the finals at the US Open. Tsonga has done well against the top 3 players and he's got the game needed to win the here. He has a huge serve and a powerful forehand, not to mention great volleys. Making him one of the few real all court players still left on tour. Because his game is well rounded, he doesn't have to rely on any one particular shot, in the way that Roddick relies on his serve, or Gasquet relies on his backhand. Tsonga, should be able to give Del Potro everything he could handle and I'd really like to see this one happen next year.
