I recently purchased a Canon SX1 (came out in the US early May) to shoot full 1080p video. If you search youtube for user mkdevo, he took some amazing video with the same camera at the Hampton Phish shows. I shot all three nights of Jones Beach and am finally getting them downconverted to 720p, adding some sound upgrades and uploading them to youtube / vimeo.
Here is my first upload... the camera is amazing for live shows since it doesn't look like a standard video camera and it's a super zoom (20x optical zoom). Highly recommended.
Lots more videos coming, third night came out the best. Subscribe to my channel to get automatically updated when I add more (should have about twenty videos up by the end of the week).
