Wayne will go platinum no matter what. His Carter series albums always sell well. Rebirth & I Am Not a Human Being both only got gold but then TCIV sold around 960,000 first week. His biggest problem is not having a hit single this time around but even without it he'll probably do at least 400k first week.
I don't really think I can predict Ariana's first week tbh because her last album was in Demi/Selena territory sales wise but this time she got 1 huge hit and 1 song that's still getting big and she seems to have more respect and credibility this time around so i'm gonna guess around 200k at most.
It's funny how you guys doubt Nicki. So far Rick Ross has the biggest selling rap album of the year with only urban support and without a hit there either. Nicki is everywhere on urban right now, Pills N Potions is currently top 10 on urban too. Plus Bang Bang and Anaconda will be pop hits and that will help a lot
