They had this postcard sized advert for it at the gig in Copenagen last year (I have it at home). There was a SMS contest on the back of it. I guess that means that it's supposed to be shown in Danish theaters (Even the text on the ad was Danish). Wether or not it will be shown in the IMAX format is a different question though. I've looked on the planetarium website (www.tycho.dk), but the only Stones news there is a showing of Live At The Max in 2006.
So whats the deal here, first they try to make you go to a theater, then buy a cd soundtrack and then buy the DVD? If it was broadcasted live I would maybe understand that, but hopefully Im wrong?
