I'm willing to bet money they won't release another video today.
This was a professionally made video, they're not releasing another one. This was a one time thing to stir up the masses in anticipation of the lineup.
It means the whole festival is going to be holographic.
I would have to agree that this video has no meaning like the picture of the round rock (honestly it looked a left over ball from the golf cart polo they have there), the Roxanne presale password, etc.
I heard from a very reliable source that all the artists names are actually spelled out in patterns in the stars of the video. They'll be sending out little decoder rings soon to everyone that purchased a wristband last year to help you figure it out. First one to decode the stars and post the line-up on the forums, wins.
