Monica Seles will retire. Out of action for three years, the beloved 33-year-old will formally call it quits and be deservingly feted.

Mid-match coaching will flop. One of the sport's virtues is the self-sufficiency it demands of players. The WTA's wrongheaded, sponsor-driven decision to let coaches provide counsel at changeovers will not only rob tennis of its tradition but also give an unfair advantage to top players, who are more able to afford the extra help.

The U.S. will win the Davis Cup. For all the Chicken Littles lamenting the state of American tennis, the U.S. has two of the world's top six players (James Blake and Andy Roddick), plus wonder twins Bob and Mike Bryan, the top-ranked doubles team. Short of Rafael Nadal's assuming Swiss citizenship, what's to prevent the U.S. from claiming the Cup for the first time since 1995?

The ATP's round-robin format will succeed. The new setup, in which players can lose an early match but not necessarily be eliminated, will cause initial confusion but ultimately be welcomed because it helps ensure that tournaments and fans get their money's worth from marquee attractions.

Roger Federer will win at least three majors. And the sun will rise in the east.
