The only way I see a woman playing in the league in the near future is if some team with low attendance does it as a publicity stunt. Right now, even the most dominant women in their respective sports would struggle against the top men, whether the sport be basketball, tennis, golf, etc. There may be advances in genetics, weight-training, nutrition, etc., that make it more likely for a woman to compete in the future, although I don't think it's terribly likely.
By the way, as an aside a woman has already signed an NBA contract. In 1980, Ann Meyers signed a contract with the Pacers and tried out for the team, but was ultimately cut.
