Okay, I'm not making this up because that's just stupid. The exact quote is: "Jay-Z's next album may be out by Thanksgiving if he finishes recording in time, sources say, and new Eminem and 50 Cent CDs, as well as a U2 greatest hits comp, may drop before Christmas." This is all on page 16 of the August 24, 2006 issue under the article titled, "Cold Summer, Hot Autumn?"
I don't usually like to post rumors, but I figured that Rolling Stone is a relatively good source and figured that people on the board would like to know. The quote doesn't say what the greatest hits comp would be, it could be different from the Best Ofs that have been released before, I don't know, to be honest, the quote is obviously very vague. I agree that it would be dumb of U2 to put out a Best Of 2000-2006 with only 2 albums, it would be a waste of songs and completely pointless. There would have to either be repeats (BD, Stuck) or most of both albums would be on the comp...
