Sasha and Kent were off the wall (FOX/Adam Rose)Will it be Melanie or Sasha? That's the question on everyone's lips leading into the finals of "So You Think You Can Dance" tonight. Sure, Marko and Tadd are still in the competition, but even the judges are comfortable saying it will likely come down to two female contemporary dancers. (Sorry, fellas!)

While we won't know who will take top honors until Thursday night, here's a look at the most notable performances from last week's Top 6, where we bid adieu to dancers Caitlynn and Ricky. With lead judge Nigel Lythgoe waffling between which woman is his favorite -- one minute, it's Sasha; the next, it's Melanie -- it's sure to be one of the best finals yet.

Zuma Zuma climbed into the "Talent" semifinals (Trae Patton/NBC)The quarterfinals of "America's Got Talent" are over, folks, and we now have our Top 16 acts. In the past four weeks, 48 acts have competed, pushing their own boundaries to the limit and sometimes beyond. We've seen countless injuries and heard off-key notes; watched dreams continue to come true and crumble right before the performers' eyes. We're all ready for next week's semifinal round. But before we move on, let's take a look at America's favorite four acts from this week.

Most Surprising: Team iLuminate
Team iLuminate is an act like no other. Yes, they're dancers, but they're dancers in the dark, using a technology that depends on every move being the right one. When the lights finally came up, everyone in the audience was on their feet, screaming so loud that the judges had to shout to be heard.

Honest critique (and real tears) from Lady Gaga, kind words from director Rob Marshall, and quick-witted banter from Emmy-nominated host Cat Deeley — not to mention some of the best dancing we've seen on TV: Last week's installment of "So You Think You Can Dance" had it all. It was a week where the judges followed America's vote, sending home this season's vixen, Jordan, and Broadway-ready dancer Jess, but no matter.

We predict this season will come down to three dancers: Melanie, Marko, and Sasha. With six dancers left in the competition, we'll have to wait to see which dancer earns top honors. In the meantime, here are the week's best performances, including a fierce same-sex number featuring Melanie and Sasha, plus the dance that famously brought Lady Gaga to tears.
