I'm taking a wild guess by saying they'll each be given one of the five songs nominated for video of the year.
The songs are..

Chris Brown - Forever
Britney Spears - Piece of Me
Jonas Brothers - Burning Up (LMAAO)
Pussycat Dolls - When I Grow Up
The Ting Tings (<333) - Shut Up and Let Me Go


Now let's take a guess on who gets what here...

Chris Brown - Status Quo
Britney Spears - Fanny Pak
Jonas Brothers - Break Sk8
Pussycat Dolls - Kaba Modern
The Ting Tings - SoReal

As long as Status Quo/Break Sk8 get stuck with the JoBros and Chris Brown it'll be a great show since I love all the other songs.
Kaba Modern is so winning this but there is hope for Fanny Pak
