Check this out: starting in "the Summer" (they don't give a specific date. Also as an upstate New Yorker, what is this Summer they speak of? I don't remember what that is...) albums are going to be released on Friday instead of Tuesday in the United States and Canada. This is an attempt to keep piracy at bay but let's be real, it's not going to. You thought I was going to tell a Pirate Bay joke, didn't you?
Nothing will until it's off the internet. Usually albums in Europe come out on Sunday or Monday, so they're thinking if it comes out in the United States before, it'll relieve piracy? When really, it'll just be the same problem, only Europe will be getting the sloppy seconds. More details here from the AV Club.
