not a chance because he won't beat Nadal in the SF. Federer can beat Novak in a SF. Chances of playing a final are close to 0%
Tactically i think fed played nadal the first set an a half well. That's what he just needs to keep doing. Annacone im sure picked up that fed nearly won every point he approached on nadal's backhand. Besides, this surface was so slower than ever it has been to play on forget that they played on a very cool low 60s degree night. Fed did well at WTF in london because of the faster court and low bounce which he will get at wimbledon and us open provided they aren't slowed down anymore. I still think if they meet at wimbledon and us open the court will be much more rewarding to fed in terms of quick points and nadal's topspin being greatly reduced.
That being said fed will have more chances that doesn't mean nadal sitll won't win. It's just that many of those ridiculous shots nadal got back on that slow ass plexicushion would be outright winners on grass or us open hard court.
I wouldn't hold your breath until fed actually wins othewrsie nadal is the obvious favorite every time.
