The stage DOES rotate.
Both the green bridges and the central stage DO rotate (and the latest does it pretty quick, by the way).
A guy from EastLink has been there this evening, and has gone down to the field, even to the stage.
Check it here:

...even though it's all in spanish and I won't translate, that's what he says (the guy who I refer to it called juliobcn and has got an african kid as his signature). He has got videos and photos of the stage, and at least one of the vids show the stage while rotating. He's been with some of the staff, and they've told him that the band is going to be there everyday from 16:00. They are NOT in any known hotel, just "private accomodation" (what the hell that means? I don't know either). On an aditional note, they are assembling some cameras on the nosebleeds, on the seated zone. Are they recording the show (this is just a question of mine), are they crazy... or are they deploying just an incredible amount of technology to provide us the best show experience??
The guys are in Barcelona, CONFIRMED.
They are rehearsing, CONFIRMED.
The stage rotates, CONFIRMED.
If there are significant updates I will make them in this post.
