Considering 20,000+ people downloaded Talk That Talk from just one site in less than 24 hours, I'm guessing Rihanna's sales have already taken a pretty big bullet...
Taylor is performing at the AMAs and will have ample time to promote her Live CD/ DVD up and down the red carpet and in any of her three potential acceptance speeches- not that she would reduce herself to promoting her material in an acceptance speech. As far as I know, none of the others listed except Bieber will be performing at the AMAs- the night before these albums are all released. It gives them an edge.
Mary, Nickelback and either Taylor, Adele or Rihanna will be top 3.
MJB and Nickelback's first couple of singles underperformed compared to their previous eras. Drake may be able to hold huge numbers in his second week. Daughtry probably won't do all that well. However, Rihanna's case is so undefined. It's doing well on iTunes already and is ahead of every other pre-order minus Drake. The radio exposure of You Da One gave her a good amount of promo, cause they announced "Talk That Talk" being released on the 21st on my radio station and I'm sure they did it on a ton of others as well. She's performing on X Factor and Ellen, and maybe (I HOPE TO GOD) on the AMAs. That exposure may be enough to get buzz for a big release, that exposure may not. It's honestly an unpredictable week. Too many factors cut in. We'll just have to see, so I honestly have NO clue what sales will be like for any album.
Out of those three probably Nickelback.
