Sister, Sister: Venus and Serena Set to Face Off Again in Australian Open Final

The dynamic duo is back at it again. Except this time, Venus and Serena Williams are on opposite ends of the court. 

Which sister will win the rivalry match this time around? 

Editor's Note: Though Serena would set the record for the most singles Grand Slams in the Open era with a win, she'd still be one title short of Margaret Court's all-time record of 24.
