It's the battle we've been expecting since the finals began: David Archuleta vs. David Cook. But the stakes will actually be higher than expected -- not because the difference between winning "American Idol" and coming in second is all that important, but because the winner may determine the show's future.
See, if Archuleta wins, which seems likely at this point, it will reveal why the future of "Idol" is in trouble. It will show that the people who presumably pick the next big music star don't actually buy music. It means that the star-making machinery doesn't actually make stars. Nothing against him -- or his tween and Grandma voting block -- but a victory for him will solidify the idea that "Idol" is no longer cool and that changes need to be made.
If Cook wins, "Idol" can point to how it still turns nobodies into somebodies. Then, if Cook goes on to live out his Daughtry-esque hit-making destiny, "Idol" can shake off the problematic sales records of Taylor Hicks and Ruben Studdard. And though he's not exactly edgy, he is compared to Archuleta.
So which David will win? Time will tell.
