I was hoping they would have the old logo, but I'm not suprised at the new one, as they have said in every interview that they aren't taking a step back, they are taking another step forward, and the new logo looks new, but is a cross between their older logo and 90s logo. I do like it however, so I don't really care.
The album cover, while not brilliant, is not that bad, and I kind of like it. Simple can be effective (as the 'black' album proved), and I think it suits the mood of the album, if it sounds anything like reviewers have made it out to sound. Very angry fist clenching stuff, which they have tried to prtray in the art. And Phloggy is right, their last few album covers haven't been that great anyway.
As for the different covers thing, they are not the only ones who have done it. Korn, Michael Jackson, and a few others spring to mind. Who really gives a shit anyway, I will just buy the album, and if the music is good, then I will be happy.
