What do you think? Prism will sell around 4,2 million IMO and R8 5 million

No.

I think that it will since Rihanna is on a hiatus pretty much and she's buliding hype. She's probably going to follow suite with the "New Rules" That Kanye, Jay & Bey have done for their projects and this could possibly stand beside her GGGB & Loud eras. Maybe even top them who knows

R8 with ease

If Rihanna promotes like how she did LOUD she will easily outsell PRISM.

A regular Rihanna release sells about 3M WW so not really, no.

It's hard to say but Katy is looking very good right now.

Don't think so, but they'll be close.

whoever is saying no, do you realize rih is coming hard this era? not a "10 month era" no more

Hard to tell since we don't know what sound she is going for, but i am interested to see her opening numbers since it looks like she will release before her usual Nov release.

We'd have to wait and see in which direction Queen of Pop's album will go. For now I'll say no.

If big hits like Diamonds and Stay barely move Unap past 1M in the US, I doubt R8 will reach 5M.

Nope

Depends if it's Pop or Urban really.

You cant really say much at this point considering we havent even heard anything from R8, If its a la loud style they might end up around selling the same

How do you know it's not going to be a 10 month era? She might release on November 2014 and then again on November 2015.
