I wasn't expecting much as far as 'new' songs being played- so I had a freakin' blast.
They were really tight and the visuals were great eye candy. The will-call dude screwed up and ended up giving us VIP wristbands. I didn't think much of this until I realized they let us all into the FRONT of the stage right before the show started. Amazing. I was right in front of Justin for most of the set. Got to watch Danny and Justin just rip shit up. It ruled.
Sometime during RS it felt like it got a lot louder... or maybe the bass was just hitting me harder so I watched the rest of the set from the hillside.
As others have mentioned, there were a few moments of them all looking around like "wait, what?". Kinda funny.
ETA: just found some more decent pix:
