Sorry, didn't read the last part of your sentence. I just figured it was more of the usual, uninformed "they're obviously tossing out the Rubin sessions because they were done a 'long' time ago" drivel. My apologies.
Your entire post is based on the assumption that the album is being delayed 2-3 months. Mine is not. If you look at it from my point of view instead of your own, I think it's pretty clear that mistakes could be repeated. And yes, I consider the track listing of HTDAAB a mistake. Not necessarily the mixes, but the track listing itself is a mess, and left many great songs on the cutting room floor. I'm just afraid that they'll forget some of the great material they wrote 6 months ago and get stuck on something they wrote at the last minute. I'm not bashing the band, I just want what any of us want...a great album.
