The official policy on recording can be read on the news page, but basically it is video recording that is not allowed. Audio recording and photos are still OK, though long lens SLR cameras and professional equipment including tripods are not. However if recording and photographic equipment are not permitted in the venue, then Mark and his management say the venue's policy will be respected. But as can be seen from other posts on this site, some people still manage to record some video.
It would be great if the official recordings were made available for fans to download, as happened during the Shangri-la tour in 2005. But as yet I haven't heard (or read) whether a decision has been made to do something similar this tour. Certainly there is nothing official available at the moment.
