|HMV in the UK is listing "Chinese Democracy" in their flyer for forthcoming releases. The flyer itself is the February edition and lists the album's release date as the 25th of April.
Since HMV is the only one listing this date, it's very unlikely this is nothing more than wishful thinking from their part. At this moment, there is no official release date for "Chinese Democracy".
At this point, it's not known where they got the date and why they printed it in the flyer.
